Frequently Asked Questions
Question: What does an Air Compressor do?
Answer: An Air Compressor compresses air, making it into a power source: pressurized air. That
pressurized air can then be used to power pneumatic tools and other things.
⚠DANGER The pressurized air generated by the Compressor is not human breathable
when it leaves the Compressor. If you want it to be human breathable, additional
equipment is
required . Refer to the current version of the Compressed Gas
Association (CGA, an ANSI-approved standards developing organization) for
information about what is required for human breathable air.
Q: Can the Compressor be installed outside?
A: Technically yes, but we advise against it. Air compressors are designed to be installed indoors. If
your Compressor is outside, the intake air will be dirtier (a significant issue), the electrical
components will be subject to extra moisture (including water), and all of the components will be
subjected to a harsher environment (cold, wind, rain, humidity, and so on). You will need special
protections and accommodations for the unit if you install it outside.
Q: What psi/bar does the Compressor provide?
A: The maximum pressure is regulated to 175 psi / 12 bar. The automatic turn-on pressure is
120 psi / 8.3 bar, the automatic shut-off pressure is 175 psi / 12 bar.
Q: What cfm does the Compressor provide?
A: 25 cfm at 90 psi / 6.2 bar, 21.3 cfm at 175 psi / 12 bar.
Q: What are cfm and psi?
A: cfm is the volume (the amount) of air being delivered. psi is the force at which that air is being
delivered. cfm stands for cubic feet per minute, psi stands for pounds per square inch.
Q: What are the motor specifications for the Compressor?
A: 7.5 horsepower, 208-240 VAC, 1 phase. Recommended breaker is 80 amps and 6 AWG wire
gauge.
60 Hz: 1,740 rpm 1/min, amps 32.8-30 A, SF amps 38-34.7 A

Important Electrical Information
⚠WARNING Electrical installation, service, and all electrical connections must be done by a
qualified, licensed Electrician who is familiar with all applicable electrical codes.
General. The motor rating, as shown on the motor nameplate, and power supply must have
compatible voltage, phase, and hertz characteristics. Make sure to have your Electrician
check all wiring connections when they are connecting the Compressor to power;
sometimes wiring becomes loose during transportation.
Wire Size. The electrical wiring between the power supply and electric motor varies according to
motor horsepower and other factors. Install adequately sized power leads to protect against excessive
voltage drop during pressure loaded start-up. Refer to the applicable electric codes in your area for
information on selecting the proper wire size and securing electrical connections. If you connect
additional electrical equipment to the same circuit, consider the total electrical load when selecting the
proper wire size.
Do not use undersize wire .
Minimum Wire Size. (Use 75°C copper wire). Make sure voltage is correct with the motor wiring.
Refer to the motor label for the running HP rating. This will determine the wire size needed.
Recommended wire sizes may be larger than the minimum set up by local ordinances. If so, the larger
wire size should be used to prevent excessive line voltage drop.
The additional wire cost is very small compared with the cost of repairing or replacing a motor
electrically “starved” by the use of supply wires that are too small. Also, if a lead wire longer than 10
feet is needed, consult a local Electrician for alternative wiring options.

Note 1: Table provides branch-circuit, short-circuit, and ground fault protection device sizes and
required copper wire size at 75°C and up to 10 feet long. For longer distances, proper
(larger) wire size must be determined and installed by local, licensed Electrician to prevent
excessive voltage drop. Refer to motor label for motor HP, voltage, and phase to determine
minimum wire size;
do not use undersized wire .
Note 2: Smaller inverse time-trip breakers and dual element fuses may be used when recommended
by a licensed Electrician. However, using an improper (too small) breaker may cause
nuisance breaker tripping, which interferes with normal operation of the Compressor and
could cause damage to the Compressor’s electric motor and other electrical components.

RS7580V-601 Rotary-Screw Air Compressor 11 P/N 5900090 — Rev. A — Sept. 2019
Fuses / Circuit Breakers. Refer to applicable local codes to determine the proper fuse or circuit
breaker rating required. When selecting fuses, remember the momentary starting current of an electric
motor is greater than its full load current. Time delay or “slow-blow” fuses are recommended.
Grounding. In the event of an electrical short circuit, grounding reduces the risk of electric shock by
providing an escape wire for the electric current. Ground terminals are identified with a ground symbol
and/or the letters “G”, “GR” or “PE” (Potential Earth).
Ground must be established with a grounding wire size according to the voltage and minimum branch
circuit requirements printed on the compressor specifications decal. Ensure good bare metal contact
at all grounding connection points, and ensure all connections are clean and tight.
⚠WARNING Improper grounding can result in electrical shock and can cause severe injury or
death. This product must be connected to a grounded, metallic, permanent wiring
system or an equipment-grounding terminal or lead. All grounding must be
performed by a qualified, licensed Electrician and must comply with all applicable
electric codes.

Installation
This section describes how to install your Compressor. Perform the steps in the order listed.
⚠WARNING Use only the factory-supplied parts that came with your unit. If you use parts from a
different source, you void your warranty and compromise the safety of everyone
who installs or uses the Compressor. If you are missing parts, visit
bendpak.com/support or call [phone], extension 191.
Safety Rules
When installing the Compressor, your safety depends on proper training and thoughtful operation.
⚠WARNING Do not install this equipment unless you have installation training. Always use
proper tools, such as a Forklift, to move heavy components. Do not install the unit
without reading and understanding this manual and the safety labels on the unit.
Only fully trained personnel should be involved in installing this equipment.
Pay attention at all
times.
Use appropriate tools and equipment. Stay clear of moving parts.
⚠WARNING You must wear OSHA-approved (publication 3151) personal protective equipment
at all times when installing the Compressor: leather gloves, steel-toed work
boots, eye protection, back belts, and hearing protection.
Tools
You may need some or all of the following tools:
•Two adjustable wrenches, one pipe wrench
•Socket and ratchet set
•Medium slot and Philips screwdriver
•Forklift
•Rotary hammer drill or similar
•Masonry bits
The Electrician may require additional tools.

RS7580V-601 Rotary-Screw Air Compressor 14 P/N 5900090 — Rev. A — Sept. 2019
Select a Location
Keep the following in mind when selecting a location:
•Clearance. You must have adequate space on all sides and above. See Clearance for more
information. Make sure the Compressor is at least 3.3 feet / 1 meter from a wall or corner, with at
least 3.3 feet / 1 meter of open space
above the unit (for good air circulation).
•Floor. Install your Compressor on a flat, dry concrete floor.
•Power. You will need a 208–240 VAC power source available near the Compressor. Use a 60
amp or greater fuse and 6 AWG wire.
•Operating temperature. The Compressor is designed to be used between temperatures of
41º to 104ºF (5º to 40ºC).
•Second floor installs. Do not install the Compressor on a second floor or elevated floor without
first consulting the building architect and getting their permission.
•Indoor installation. Your Compressor works best with clean, dry air, which is found indoors. If
you install the Compressor outdoors, the air is wetter and dirtier; outside air
must be filtered
before it can be used with the Compressor.
•Ventilation. Install the Compressor in a well-ventilated area, away from sources of contamination
such as dirt or dust. You do not want the Compressor pulling in the same air that just came out of
it; that air is hot and dirty, not suitable for air intake. Installing the Compressor in a dust-filled
environment is not acceptable; it will damage the Compressor and it voids your warranty.
⚠DANGER The pressurized air generated by the Compressor is not human breathable when it
leaves the Compressor. If you want it to be human breathable, additional
equipment is
required . Refer to the current version of the Compressed Gas
Association (CGA, an ANSI-approved standards developing organization) for
information about what is required for human breathable air.

RS7580V-601 Rotary-Screw Air Compressor 15 P/N 5900090 — Rev. A — Sept. 2019
Moving the Compressor
There are two appropriate ways to move the Compressor:
•Move the Pallet the Compressor is on using a Forklift. One way to move your
Compressor to the desired location is to use a Forklift from underneath while the Compressor is
still on its pallet. Make sure the Compressor is firmly secured to the Pallet before moving it.
•Move the Compressor from Above using the Two Eye Bolts. The Compressor comes
with two heavy-duty, silver Eye Bolts, which can be used—together—to lift the Compressor from
above. Use great care if you decide to lift the Compressor from above using the Eye Bolts. Make
sure the Eye Bolts are securely in place before lifting the Compressor using them.
⚠WARNING You must use both Eye Bolts; do not lift the Compressor from above using only
one of the Eye Bolts.

RS7580V-601 Rotary-Screw Air Compressor 16 P/N 5900090 — Rev. A — Sept. 2019
Remove the Stabilizing Bars
The Compressor ships with two Stabilizing Bars in place to help keep it secure during transport.
You can remove them when the Compressor has been moved to its permanent location.
⚠CAUTION If you wish, you can leave the Stabilizing Bars in place. If you do, avoid hitting them;
they have sharp corners and you could be injured.
One Stabilizing Bar is between the Electrical Box and the Motor; the other is below the Oil Separation
Tank.
Note: The Stabilizing Bars are in different locations on some older models of the RS7580V-601.
To remove a Stabilizing Bar, remove the Nuts and Bolts holding the Stabilizing Bar in place, then
remove the Bar.

RS7580V-601 Rotary-Screw Air Compressor 17 P/N 5900090 — Rev. A — Sept. 2019
Clearance
The Compressor has two clearance zones:
•Ventilation/Maintenance. Always keep at least 3.3 feet / 1 meter completely clear around the
Compressor, even if it is in a corner or against a wall. This ensures an unobstructed flow of air to
the Compressor and allows adequate space for maintenance.
Required .
•Safety Exclusion Zone. BendPak strongly recommends keeping 6.6 feet / 2 meters clear
around the Compressor for safety purposes. Only trained personnel should be allowed in the
Safety Exclusion Zone; nothing else—no half-finished projects, no wires or cables, no storage,
no chemicals, no things you’re going to get to next week.
Strongly recommended .
⚠DANGER When you even hear the words “air compressor,” you need to remember that being
in close proximity to one is a serious endeavor with potentially life-threatening risks.
The Compressor can start without warning. An accidental quarter turn on a ball
valve can unleash pressurized air at potentially dangerous levels. Only allow trained
personnel near the Compressor.
Do not assume you are going to be safe

Anchor the Feet
If desired, you can anchor each of the four feet on the Compressor. This provides extra stability for the
unit. Anchoring the feet is optional; anchor bolts are not provided.
Important: Whether you decide to anchor your Compressor or not, remember to use the supplied
Anti-Vibration Pads between the Compressor feet and the ground.
Recommended Anchor Bolt specifications: wedge anchors; 3/8 in wide by 3.5 in deep; torque to 55
pound feet.
To anchor the Compressor feet:
1. Make sure the Compressor is in the desired location.
Once anchor bolts are torqued into position, they are not easily removed. BendPak strongly
recommends making sure the Compressor is in the desired location
before anchoring it into
place.
2. Put the Anti-Vibration Pads under the feet of the Compressor.
3. Using the holes in the feet as guides, drill the holes for the Anchor Bolts through the Anti-Vibration
Pads and into the concrete.
Go in straight; do not let the drill wobble.
Use a carbide bit (conforming to ANSI B212.15).
The diameter of the drill bit
must be the same as the diameter of the Anchor Bolt. So if you are
using a 3/8 inch diameter Anchor Bolt, for example, use a 3/8 inch diameter drill bit.
4. Use a vacuum to thoroughly clean each hole.
If a vacuum is not available, use a wire brush, hand pump, or compressed air.
Do
not ream the hole. Do not make the hole any wider than the drill bit made it.
5. Put the washer and nut into place, make sure the top of the nut is flush with the top of the Anchor
Bolt, then insert the Anchor Bolt into the hole.
6. Hammer or mallet the Anchor Bolt down into the hole.
Stop hammering when the washer is snug against the top of the foot.
7. Wrench each Nut
clockwise to the recommended installation torque, 55 pound feet, using a
torque wrench.
Important: Do
not use an impact wrench to torque the Anchor Bolts.
Wrenching the nut forces the wedge up, pushing out the expansion sleeve and pressing it tightly
against the concrete.

RS7580V-601 Rotary-Screw Air Compressor 19 P/N 5900090 — Rev. A — Sept. 2019
Connect to a Power Source
The Compressor must be connected to an appropriate power source.
⚠DANGER All electrical work must be done by a licensed, certified Electrician in
accordance with all applicable local electrical codes. Damage caused by improper
electrical installation may void your warranty.
All electrical work
must conform to applicable local, state, and federal codes, rules, and regulations,
such as state and federal OSHA regulations and electrical codes. The Compressor
must be
grounded.
Important: BendPak recommends having your Electrician check all wire connections inside the
Electrical Box; sometimes they can become loose during transport.
Based on what’s best for your specific location, most customers have their Electrician:
•Wire the Compressor directly into the facility’s electrical system, or
•Add a power cord with appropriate plug to the Compressor, which is then plugged in to an
appropriate power source.
The Electrician will need to provide these components; they are
not supplied with the Compressor.
There is a hole in the bottom of the Electrical Box (labelled Power In on the inside) specifically for
wiring the Compressor to a power source.
Important: The Compressor uses electrical energy and creates pneumatic energy; if your
