HCF

Compact HCF Series

Features

The exclusive design of the internal rotor motor, with the wrap around impeller hub, provides maximum performance with extra- slim depth which requires the minimum of space for installation.
This characteristic, together with the special design of the frame or casing enables us to offer extremely light weight fans with slim profiles ensuring an extgremely highperformance.
The COMPACT series is available in 3 different versions:

- wall mounting
- cylindrical cased duct mounting
- portable coolers

Construction

Wall mounted
The mounting plate is formed from a sheet steel stamping except for the 710 model which has a mounting plate made from injection moulded plastic. The motor support is manufactured from steel rod and supplied with a steel wire finger proof guard.
The terminal rod is fitted on the motor. The whole assembly is protected with a black polyester paint.
In the standard version, the direction of flow is: motor to impeller (Form A).

Cased cylindrical duct mounted

The casing is constructed from rolled steel plate and the motor support from steel rod electro-welded, both protected with a black polyester paint.
Flange dimensions are to ISO 6580.
The terminal box is fixed on the outer side of the casing. In the standard version, the direction of the flow is: impeller to motor (Form B).

Portable cooler

The flanged tubular outer casing is laminated in steel plate.
Motor support is of steel rod electro-welded.
Tubular stand in cold formed steel tube.
The casing incorporates a specially designed bell mouth and guards in steel mesh.
The whole assembly is protected with black polyester paint.
The terminal box is fitted on the outer side of the casing and is provided with a two-pole on/off switch.
In standard version the direction of the flow is impeller to motor (Form B).

All the COMPACT fans are available with a die cast aluminium impeller

A comprehensive range of mounting accessories are also available for ease of installation.

Motors

Asynchronous induction motors with squirrel cage rotor in the cast aluminium in accordance with CEI 34-1. The rotor is dynamically balanced in accordance with ISO 1940. The motor casing is constructed in die cast aluminium with cooling fins and finished with a black polyester paint:
Supply voltages and frequencies

- 230V 50Hz single-phase (220V 50Hz for 2 pole motors)
- 230/400V 50Hz three-phase (220-380V 50 Hz for 2 pole motors)
- 400V 50Hz three-phase

For single-phase units, the capacitor is enclosed within the terminal box.
The wall version and cased version include 9 standard diameters from 250 to 710 mm and, depending on the model, are fitted with single-phase or three-phase motors in 2, 4, 6 or 8 poles. Volume flow ranging from 500 to 22400 m³/h. The portable version includes 3 standard diameters (315, 400 and 630 mm) and is supplied with a 4 pole motor.

- totally enclosed IP65- class F (working temp between -40°C to 70°C)
- thermal overload protection incorporated in the winding with connections to the terminal box
- suitable for speed control (except 2 pole motors and 4-pole 630 mm single phase models).

Impellers

Made of injection moulded plastic reinforced with chemically anchored fibreglass.
They are manufactured colour red UV stable and dynamically balanced to ISO 1940.
The impeller of the 710 models is made in die cast aluminium. In standard versions the blade angle is 32° or 34° depending to the model.
They can be provided with a low blade angle (21°).
