Inline сentrifugal fan
Assignment
Inline сentrifugal fans MARS is intended for application in rooms of residential and public buildings, and also in auxiliary
buildings of the industrial enterprises.
Safety requirements
Base on type of protection from electric shock the fans relate to the class I devices per GOST(all-union State Standard)
12.2.007.0-75. The level of fan protection against dangerous parts and water is IP X4. The level of motor protection
against dangerous parts and water is IP44.
ATTENTION!
Fan operation outside the specified temperature range (from -25C to +70C) is prohibited. It is prohibited
to install fan in the same air vent line together with smoke emission pipe of the fuel burner device.
ATTENTION!
All options, including linking, configuration, maintenance and repair must be performed only when
the main voltage is o.
Electricians with special access to the executed work, install fans.
Disconnecting items from a network have to be built in stationary conducting, according to installation
rules. The disconnecting device has to disconnect all poles. The ground cable shouldn’t be broken o.
ATTENTION!
The equipment can not be used by persons (including children) with limited physical, mental or intellectual
abilities or if they have no skills or knowledge, unless they are controlled or instructed how to use
appliance by a person responsible for their safety. Children must be under supervision to avoid playing
with the device.
Main technical characteristics MARS
MARS fans is issued seven standard sizes depending on the install housing diameter.
Fan look, basic dimensions, connecting sizes and technical characteristics described in pic.1 and lists of dimensions

Example
MARS GDF 100
“ERA” fans are manufactured according to specs 4681-007-96059883-2016, valid rules and standards. Fans are
intended for alternate current network connection of 220-240 V voltage and 50 Hz frequency (allowed to use the fan
at a frequency of 60Hz).

Wiring diagram MARS
• switch o the fan;
• disconnect it from air ducts and air dispensers and
remove from the installation site;
• remove dust from blades of the driving wheel, using a
soft dry brush or cloth;
• clean blades of the driving wheel, using soapy water;
• wipe all plastic parts with a soft cloth dampened with
soapy water;
Fan connection to a network
Maintenance
Installation:
The length of the well-established pipeline from the fan should be at least 1000 mm. A shorter pipeline should be
equipped with a rigid lid/grid that complies with EN ISO 13857: 2008.
