EBB 170 N T IP44 small centrifugal fan with filter

Cabinet

The cabinet is made of impact-resistant plastic, the colour is white. The cabinet is designed for wall or ceiling mounting. There is a return flap in the fan discharge. The front panel contains a stainless steel filter grille. When the front panel is removed, the power supply is automatically disconnected.

Running wheel

The impeller is radial with forward curved blades. The impeller is statically and dynamically balanced.

Motor

The motor is a three-speed asynchronous motor with a start-up capacitor. The motor has thermal protection against overheating. The maximum operating ambient temperature is 40 ˚C. Double insulated design, IP44 protection.

Square box

The terminal block is accessible by removing the front grille and terminal cover, connecting flush or cable on plaster. The terminal block includes a relief clip to prevent the cable from being pulled out.

Speed control

Speed control for type S using the REB stepless controller or the INTER 4P or COM 3 speed switch. On type T, the speed is automatically switched by a built-in time switch. See wiring on next page.

Noise

The noise emitted by the fan is measured at a distance of 1.5 m in the axis of the fan on the suction side.

Variants

- S - basic three-speed design
- T - 2-30 minutes run time, fan runs at lower speed
- HT - 1-30 minutes run time, fan runs at lower speed, built-in hygrostat

Mounting

Mounting is done on the wall using the paper mounting template included in the delivery. Dowels and screws are also included. When the front grille is removed, the fan is automatically switched off by the built-in safety switch. During installation, we recommend flexible pads under the fan mounting points to reduce noise transmission through the building structure.

Instructions

Three-speed fans are suitable for relatively long ducts with greater pressure drop or for direct through-wall ventilation. The fans can be used for ventilation in residential construction, in conjunction with a HIG 2 hygrostat or a hygrostat combined with a thermostat for ventilation of wet areas.
