GuardAir N552B Series User manual

OPERATING INSTRUCTIONS
FOR GUARDAIR STANDARD, NED AND PULSAIR™ COMPRESSED AIR-POWERED VACUUMS
Please save these instructions and the accompanying replacement
parts information for your future reference.
FOR YOUR SAFETY
Turn off all compressed air connections with the
compressed air source at the nearest valve. Disconnect
compressed air connections only after the compressed
air supply has been turned off and the air supply hose
vented by opening the valve on the vacuum head. NEVER
disconnect a pressurized compressed air hose.
AIR SUPPLY
An adequate supply of compressed air is essential
for the proper performance of your Guardair vacuum.
Compressed air requirements for vacuum units and
vacuum generating heads equipped with the following
Venturi types are listed below:
“Dual B” Venturi
N552B Series .....................................................................110 cfm
“B” Type Venturi
N551B Series, N301B Series ................................................68 cfm
“D” Type Venturi
N551D Series, N301D Series, N201DC, N101DC ..................47 cfm
“S” Type Venturi
N201SC, N101SC ................................................................20 cfm
“M” Type Venturi
N101MC, N051MC...............................................................20 cfm
Please note that these requirements are for compressed
air volume, not pressure. The recommended compressed
air inlet operating pressure is 100 psi for all vacuum units.
All units will function at lower operating pressures, but
with a corresponding reduction in performance.
Units featuring a “B” or “D” Type Venturi include a
Chicago-style connector. A 3/4” ID or larger compressed
air supply hose is recommended for these models.
Units featuring an “S” Type Venturi include a 1/2”
industrial interchange male connector. A 1/2” ID
or larger compressed air supply hose is recommended for
these models. Units featuring an “M” Type Venturi include
a 3/8” industrial interchange male connector. A 3/8” ID
or larger compressed air supply hose is recommended for
these models.
FOR ALL MODELS: To ensure maximum performance,
clean or replace the internal filter as necessary. In
addition, clean or replace the exhaust silencer (inside
the exhaust housing) as necessary. Inspect the cover
gasket for deterioration and replace if necessary. On
all vacuum units, use of a smaller diameter air hose or
smaller size air fittings will seriously restrict performance.
Use the recommended hoses and fittings.
Be certain that the drum has no dents along the seams
and is airtight. The cover gasket under the vacuum
generating head must form a complete seal with the
top edge of the drum.
CAUTION: Drums used with Guardair vacuum generating
heads must meet the steel gauge requirements in the
table below. Thinner gauges of steel run the risk of
drum collapse.
DRUM 55 gal 30 gal 20 gal 10 gal 5 gal
GAUGE 19 18 18 20 20
REPLACING GASKETS
On 55, 30 & 20 Gallon Models, remove the gasket to be
replaced. On the new gasket, remove the protective tape
covering the adhesive, then apply gasket to lid.
On 10 & 5 Gallon Models, the lid gasket is adhered to
the lid by hot glue. The hot glue can easily be removed
with rubbing alcohol. Let the rubbing alcohol sit for one
minute, then simply peel off with a flat head screwdriver.
We recommend using hot glue when installing new gasket.

SET-UP AND OPERATION, 55-GALLON, 30-GALLON
AND 20-GALLON MODELS:
Place the vacuum generating head on the drum. There
are no clamps required to form an airtight seal. When
the vacuum is in operation, the negative pressure within
the drum will create the airtight seal between the head
and drum.
Connect the vacuum hose to the vacuum generating head
by inserting the hose adapter into the inlet elbow. Slip the
hose end onto the adapter. Connect vacuum attachments
to the vacuum hose.
Turn off the compressed air supply valve at the compressor.
B & D Venturis
Connect the compressed air supply hose to the vacuum
generating head via the Chicago-style coupler. Twist to-
gether and be sure they lock. Install the safety clips.
Connect the compressed air supply hose to the compressor.
Turn on the compressed air supply. Open the shut-off
valve to operate.
S Venturis
Connect the compressed air supply hose to the vacuum
generating head via the ½” industrial interchange male
connector. Connect the compressed air supply hose to the
compressor. Turn on the compressed air supply. Open the
shut-off valve to operate.
Liquid Shut-off Accessory
Before picking up liquids, remove the internal filter, which
is held in place by three springs. For continuous liquid
pick-up, the liquid shut-off accessory (optional) should be
installed in place of the internal filter and held in place by
the same three springs.

SET-UP & OPERATION, 10-GALLON MODELS:
The vacuum generating head, which mounts on top of the
drum, seals to the drum via the lid clamps.
Connect the vacuum hose to the vacuum hose inlet by
slipping the hose end onto the connector. This is an
intentionally tight fit. Connect vacuum attachments to
the vacuum hose.
The vacuum comes with a liquid shutoff assembly built
internally within the cartridge filter. The cartridge filter
can be removed for maintenance or replacement by
removing the wing nut and washer on the bottom of
the filter.
Turn off the compressed air supply valve at the compressor.
Model N101DC - Connect the compressed air supply
hose to the vacuum generating head via the Chicago-style
coupler. Twist together, making sure that they lock. Install
the safety clips. Connect the compressed air supply hose
to the compressor. Turn on the compressed air supply.

STATIC CONDUCTIVE MODELS:
Guardair manufactures NED (non-electrical discharge)
models, designed to eliminate static electricity by
incorporating static conductive components to suppress
static electricity charges. Should stray static charges
become generated, these charges are immediately
dissipated through the electrically interconnected,
static conductive components. For an added measure
of protection, users can ground the vacuum by connecting
the grounding lug to an external electrical ground using a
grounding clamp and cable (available as an accessory item).
To ensure proper electrical bonding (connectivity between
components), make sure that only static conductive,
factory-supplied parts and accessories are used with
Guardair NED vacuums. All components must fit together
firmly, including the static conductive vacuum hose, which
must mount securely on the vacuum hose inlet, and all
static conductive vacuum accessories.
Always inspect all static conductive vacuum components
before use, and replace worn or rusted parts as needed.
If you have questions about the necessity for grounding,
consult with a qualified safety engineer.
PULSEAIR™MODELS:
PulseAir Vacuums/Dust Extractors incorporate proprietary
PulseAir technology engineered to clean the vacuum filter
without routinely opening the unit. By activating the
PulseAir System, a burst of compressed air is injected
into the interior of the filter mounted beneath the vacuum
lid. Dust particles clogging the outer filter surface are
dislodged and settle within the closed container.
In addition to automatic filter cleaning, PulseAir Vacuums/Dust
Extractors are equipped with HEPA filtration to comply
with OSHA Silica Dust Regulation 29 CFR 1926.1153.
PulseAir Vacuums/Dust Extractors also come standard
with a cloth pre-filter bag to provide enhanced filter
protection and extend filter life, as well as static
conductive components to eliminate nuisance shocks.
Operation: Connect PulseAir Vacuum/Dust Extractor to
compressed air source using air supply hose provided.
Switch ball valve to OFF position by turning 90 degrees
clockwise. Locate button on PulseAir System beneath
venturi housing on top of vacuum lid. To activate, press
button and release. Depending upon filter age and surface
dust concentration, pressing button between two (2) and
ten (10) times should be sufficient to clean filter. Wait at
least two (2) seconds between each press for system
to reload.
IMPORTANT - Do not activate PulseAir System when
vacuum is in operation. Only activate when four (4)
latches clamping vacuum lid to vacuum drum are
secure. PulseAir Vacuums/Dust Extractors do not
include a liquid shutoff device. Vacuuming liquids is
therefore not recommended.
Replacing Cartridge Filter: Unsecure latches. Remove
pre-filter bag by disengaging the worm gear clamp. Detach
three (3) retaining springs from cartridge filter cage and
from vacuum lid. Gently remove pre-filter bag and
cartridge filter. Do not shake pre-filter bag or cartridge
filter to avoid releasing and spreading dust and
containments. Also check interior of the cloth pre-filter
bag and empty out dust and debris if necessary.
Fit fresh cartridge filter underneath vacuum lid. Attach
one end of each retaining spring to filter cage and oppo-
site end to ring under vacuum lid. After filter is secured in
place, slide pre-filter bag over cartridge filter and fasten
with worm gear clamp. Place vacuum lid on top of vacuum
drum and re-fasten latches.
PulseAir™Dust Extractors: Designed specifically for
point-of-source dust collection applications or source
capture power tools. Connect vacuum hose via hose
cuff to dust port outlet on the power tool. Additional
hose cuff sizes are available to provide proper
dust port connectivity.
