ERA Commercial Fans

Designed for inline mounting into any point of ventilation system and at any angle.

Works in supply or exhaust mode depending on how it is mounted into the ventilation system.

Fan casing is made of high-quality durable plastic.

Waterproof terminal box.

Single-phase ball-bearing external rotor motor is supplemented with a centrifugal impeller with backward-curved blades. It is also implemented with overheat protection and automatic restart.

Mounted to wall and ceiling surfaces with special holding brackets (purchased separately).

Smooth or step speed regulation is available. Speed adjustment is done by means of a thyristor or autotransformer speed controller. Several fans can be connected to the same speed controller device, provided that their total power and operating current do not exceed the rated speed controller parameters.

Ingress protection rating for electrical equipment is IPX4, for motor - IP44.

Capacity characteristics range from 450 m³/h to 1 150 m³/h. Designed for supporting an air intake sufficient for industrial equipment operation. Powder-coated corrosion resistant casing is made of cold-rolled steel (CRS). Equipped with a forward-bladed impeller made of galvanized steel. Fitted with an external rotor motor. Implemented with a metal mesh protecting the input flange against intrusion. Capacity and air pressure regulation is possible with speed controllers of RS-V/RS-N series. Insulation: class B. Ingress protection rating: IP44. Service life: 10 years

STELS duct fan in a compact galvanized steel casing is designed to organize air exchange in supply and exhaust ventilation systems. It has the lowest mounting height among commercial fans manufactured by ERA Group.

Ideal for rooms where installation space is scarce. The fan does not lose any technical parameters and maintains high performance. STELS is mounted in the ventilation duct in any position.
The fan is equipped with a single-phase motor on ball bearings with external rotor, which is equipped with an impeller with backward curved blades.
The motor has thermal protection with automatic restart.
The connection is made in a sealed terminal box equipped with diaphragm seals.
Rubber seals on the flanges simplify installation and provide a reliable seal without the need for additional materials.
Lifespan: 5 years
Operating temperature: -25 to +60 °C

Ingress protection: IPX4

ERF roof fans are designed to be used in residential, industrial and public buildings for air extraction and for elimination of non-explosive gas mixtures

For outdoor application at temperatures from -30 to +60 °C. The fans are designed to be installed on the roofs of different types in a horizontal position only. It is also important that the rotational axis of the motor is to be set vertically. Mounting is to be done on a specially prepared base or onto the roof output of a ventilation shaft (air duct).

ERF is equipped with a single-phase induction motor with an external rotor and an armature with the high ohmic resistance. Also implemented with a self-resettable overheating protection with a restart. Has IP54 rating: motor protection from water and contamination of dust and other particles. F-class insulation provides higher reliability and durability of the motor making it resistant to high temperatures. The casing is made of galvanized steel and additionally protected by a polymer coating from environmental influences
