Special Conditions for Safe Use:
The unterminated power cable (ying leads) must be terminated by the end user in the eld
according to installation standards, IEC/EN/ABNT NBR IEC 60079-14, to a suitable safe power
location, or under one apparatus or enclosure in one of the protection concepts for use
in hazardous locations. Flying leads consist of a brown “Hot” wire, blue “Neutral” wire and
yellow/green “Ground” wire.
T6 Temperature Classication:
85°C T6 - According to IEC 60079-0 / EN 60079-0 / ABNT NBR IEC 60079-0.
To ensure that there is no risk of ignition due to hot surfaces, the equipment is classied with
regard to the maximum surface temperature of any part of the equipment while in operation
based on the ambient temperature of 40°C. Equipment must be selected with a suitable
temperature classication for the gases and vapors present where the equipment is to be
installed. Ensure that the maximum surface temperature of any parts of the equipment are
below the ignition temperature of the explosive atmosphere concerned.
This equipment is intended for use in ambient temperatures ranging between -20°C and
+40°C.
The letter “X” at the end of the ATEX, IECEx, and INMETRO certicate numbers
indicate a special condition for safe use. This special condition of safe use refers
to the fact that the Hazardous Location Fans referenced herein are supplied
without an AC power plug termination for the power cable.

Flame Proof Enclosure: Ex d IIB
The electric motor consists of one ameproof enclosure, which contains less than 6%
magnesium by weight. The on/o switch is housed within the motor enclosure, and is
operated by a shaft, extending out from the rear end bell to a lever. The lever is accessible via
an attached push rod.

SM-EFATEX Rev E - Page 3 of 13
Motor connections are made through a non-detachable cable, secured to the motor with
an approved Flame Proof cable gland from the company Hawke, model 501/421/0/M20
and complies with International Standards EN 60079-0, EN 60079-1, and EN 60079-7. The
electric motor drives an aluminum or plastic fan blade which is enclosed in a plastic, statically
conductive housing with a conductivity rating of <1 giga ohms. Connection to the motor is
facilitated by a Terminal Block mounted in an Increased Safety/Flame Proof Enclosure rated
II 2 G Ex e II T6, from the company Rose Industries, Part Number 05080806, and covered
under ATEX Certicate No. PTB 00ATEX1063. This box was designed to conform to
International Standards EN 60079-0, EN 60079-1, EN 60079-7, EN 61241-0 and EN 61241-1.
The enclosure features stainless steel grounding lugs, with a high heat silicon gasket.
The Flame Proof enclosure has attached, approved, explosion proof cable glands, as
described below.
Rated: II GD Ex e II
Type: Polyamide Ex metric conforms to International Standards EN 60079-0, EN 60079-1, EN

The power cables are not terminated with power plugs. See Special Conditions for safe use.
The fans are assembled with both Inlet and Outlet Safety Guards that conform to the safety
standards to prevent danger zones being reached by upper limbs in the BS EN ISO 12100
Safety Machinery – Guards Standard.
Installation and Start-Up
During the installation and start-up of the RAMFAN blowers in areas where there is a risk of
explosion:
• Design of the electrical installations must be in accordance with EN/IEC/ABNT NBR
IEC 60079-14.
• Ensure power source is providing an electrical ground.
• Blowers must be integrated into a system in a way to support accessibility for
regular maintenance.
• Blowers are designed for portable, nonxed installation. Blowers have no mount
ing features to support rigid duct or x installations.
• Perform careful inspection of each blower system to ensure ducting is securely
attached to blower. All components of the blower system are made of electrically
conductive material. It is very important to properly and securely attach each component to
maintain a ground path.
• Ensure set-up, installation, operation and maintenance are performed only by
properly trained personnel.
• Operation after a faulty installation or maintenance shall be considered as
unintended use.
INSTRUCTIONS AND CARE

SM-EFATEX Rev E - Page 4 of 13
Before STARTING the FIRST time
DO NOT start operation if there are any signs of shipping damage to the blade, guards or
housing. STOP, call your dealer. USE Ex-Rated receptacles for this equipment. IT IS NOT
recommended to use extension cords for high amperage load. (See power rating label on
limit).
OPERATION
Always ensure the switch is in the “Down/OFF” position prior to connecting the ventilator to a
power source.
Stop the blower if mechanical noise, vibration or other abnormal conditions occur. Any noise
other than turbine-type pitch is not normal.
This unit is equipped with thermal overload protection with automatic reset. Motor will
restart without warning after protector trips. To protect the user, disconnect unit and
determine cause of protector trip.
Conductive RAMFAN Portable Ventilators are made with statically conductive materials.
When ducting is required is required to remote the ventilator from the point of application in
a potentially explosive environment, the ducting must be:
1. Statically Conductive, Surface resistance ≤106 ohms.
2. Flexible.
3. Reinforced with integrated helical steel wire, spaced to prevent duct material
from collapsing, when airow is inadvertently blocked on suction side of duct.
MAINTENANCE
• Disconnect power before inspection, disassembly or cleaning.
• Never immerse or directly spray motor with liquids.
• Clean ventilator with commercially available biodegradable cleaning solutions. Do
not use solvents containing hydrocarbons (i.e. MEK, Acetone).
• Inspect clearance between impeller tips and fan casing for minimum acceptable
clearance with pin gauges as shown in picture below. Minimum acceptable
impeller tip clearance is 0.079” / 2mm.
• Clean fan, impeller, & motor to remove accumulated dust or debris. Clean the
impeller and motor with a damp cloth only, to avoid any possibility of a disruptive
breakdown due to electrostatic charging.
• Inspect impeller & nger guards annually for damage. Replace as necessary.
• There are no user serviceable parts. Contact factory for replacement part
applicability.
• Do not change make or model number of motors for any reason!

SM-EFATEX Rev E - Page 5 of 13
CAUTIONS
Do not move ventilator while fan is in operation. Use good lifting practices when moving
ventilator to prevent bodily injury.
Blower should be operated and repaired by trained personnel only.
Do not operate if there is any physical damage to cord, plug or receptacle.
Keep ngers and hands clear of fan blade. Keep fan guard securely in place. Do not operate
with damaged or missing fan guards.
Use properly grounded power receptacle in potentially explosive atmospheres, and for
operation safety. Ensure continuity to the earth.
Fatal electrical shock may result if motor frame and adjacent metal are not grounded in
compliance with electrical code.
Keep area clear of rock and debris.
Keep away from children.
WARRANTY
Positive Pressure Ventilators Turbo Ventilators and portable blowers, excluding motor
and wear items, are warranted for one year from date of original purchase, to be free of
defects in material and workmanship. Electric motors are warranted by their respective
manufacturers. Wear items include feet, fasteners, handles, wheels, and paint are not
covered under the warranty. Fan impellers and shrouds are warranted to be free of defects
in material and workmanship for ve years. Components exposed to salt water service are
warranted for a period of one year from date of original purchase. Duct is not warranted due
to its intended use.
Authorization for warranty repairs must be obtained from the factory. There are no
other warranties expressed or implied.

Fan Performance Characteristics
Fan performance is characterized as airow as a function of backpressure. Backpressure is
typically a function of the length of exible duct attached to the fan.
Maximum airow also referred to as free air occurs at 0 mm/ 0” w.g.
The rst chart shows 4 performance curves for all four ATEX fans running on 50Hz AC power.
The second chart show 3 performance curves for three of the ATEX fans, running on 60Hz.
Please note that the EFi120xx is not designed to run eciently on 60Hz AC power and does
not appear on the 60Hz chart for this reason.
