Applicable Models:UB20xx、EFi150xx、EFi75xx、EFi120xx

Special Conditions for Safe Use

The letter "X" at the end of the ATEX, IECEx, and INMETRO certificate numbers indicates a special condition for safe use. This special condition of safe use refers to the fact that the Hazardous 

Locations Fans referenced herein are supplied without an AC power plug termination for the power cable.

The un-terminated power cable, (flying leads), must be terminated by the end user in the field 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.

T6 Temperature Classification

*According to IEC 60079-0 Ed.6 / EN60079-0:2012 + A11: 2013 / ABNT NBR IEC 60079-0:2008 +Errata 1:2011. 85°C T6

To ensure that there is no risk of ignition due to hot surfaces, the equipment is classified 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 classification for the gases and vapors present where the equipment is to be installed. Ensure that the maximumsurface 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.

Description of Apparatus

The Portable Ventilator assemblies represented herein consist of an Approved Explosion Proof 

Electric Motor Rated: Ex d IIB by Bluffton Motor Works (Formerly Franklin Electric) as listed below and are covered by Certificate No. DEMKO 03 ATEX 134885U.

The Flame Proof Electric Motor

Power Requirements: See chart above.

Ambient Temperature Range: -20°C

Ingress Protection to IEC 529: IP55

Marked: (“Bluffton Motor Works”) Electric Motor for Hazardous Locations. 

Flame Proof Enclosure: Ex d IIB

The electric motor consists of one flameproof enclosure, which contains less than 6% magnesium by weight. The on/off 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.

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 60079-0:2012, EN 60079-1:2007, EN 60079-7:2007. 

The electric motor drives an aluminum or plastic fan blade containing less than 6% Magnesium by weight 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 No. 05080806, and covered under the certificate No. PTB 00ATEX1063. This box was designed to conform to International Standards EN 60079-0:2012 + A11:2013, EN 60079-1:2007, EN 60079-7:2007, EN 61241-02006, EN 61241-1:2004. The enclosure features stainless steel grounding lugs, with a high heat silicon gasket.

The Flame Proof enclosure has attached, approved, explosion proof cable glands Rated: II GD Ex e II.

Type: Polyamide Ex metric conforms to International Standards EN 60079-0:2012 + A11:2013, EN 

60079-1:2007, EN 60079-7:2007, EN 61241-02006, EN 61241-1:2004.

Material: Polyamide Color: Black/Blue

Grommet: NBR Protection classification: IP68

Temperature range: -4°F to +212°F Approval: PTB 00 ATEX 1063

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 294:1992 Guards Standard.

INSTALLATION & START-UP

During the installation and start-up of the Euramco Safety blowers in areas where there is a risk of explosion:

Design of the electrical installations must be in accordance with EN/IEC/ABNT NBR IEC60079-14.

Ensure power source is providing an electrical ground.

Blowers must be integrated into a system in a way to support accessibility for regularmaintenance.

Perform careful inspection of each blower system to ensure ducting is securely attached toblower. All components of the blower system are made of electrically conductive material. It is very important to properly and securely attach each piece to maintain a ground path.

Ensure set-up, installation, operation, and maintenance are performed only by properlytrained personnel.

Operation after a faulty installation or maintenance shall be considered as unintended use.

Before STARTING the FIRST Time

DO NOT start operation if there are signs of shipping damage to 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 OFF position prior to connecting a 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.

To protect the user, this unit is equipped with thermal overload protection with automatic reset. Motor will restart without warning after protector trips. If motor thermal protector trips, disconnect unit and determine cause.

Conductive RAMFAN Portable Ventilators are made with statically conductive materials. When ducting is required to remote the ventilator from the point of application in a potentially explosive environment, the ducting must be statically conductive and properly secured to ventilator to minimize the potential fan static electricity build up.

MAINTENANCE

Disconnect power before 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).
