Features & Benefits


An extensive range of nine sizes from 100mm to 315mm diameter, which means greater performance choice.

Ease of installation

All models are designed for direct connection to standard diameter flexible or rigid circular ducting with 25mm long spigots for ease of connection.


Each unit has a heavy gauge pressed steel housing, which is durable, long lasting and corrosion resistant.

Easy assembly

The integral mounting bracket provides a fast, simple approach to fixing the fan in position.

Quality impellers

A high efficiency, single inlet, single width backward curved centrifugal impeller which is designed to be non overloading and self cleaning.

Tested to the very latest standards

HIT units are tested to ISO 5801:1997 (airside performance) and to BS 848 Pt 2:1985 (sound performance) at Elta Fans own test facility, meaning accurate, up to date information on performance and noise data that can be relied upon.


Each HIT has a 12 month warranty.


HIT casings have a galvanised pressed sheet steel construction, providing a robust, long lasting and corrosion resistant casing. The inlet and outlet spigots should be a minimum of 25mm long to enable the installation and fixing to circular rigid, or flexible ductwork. All HIT units are to be supplied complete with integral mounting brackets manufactured from galvanised sheet steel for horizontal or vertical mounting arrangements.


All motors are to be highly efficient, three speed external rotor motors; matched to the aerodynamic performance of the impeller. Motors have sealed for life ball bearings to enable the fan to be mounted at any angle. Motors are protected to IP44 with Class F insulation; suitable for speed control and ambient operating temperatures up to +50°C with built in thermal overload protection. Non self-resetting thermal cut-outs are fitted in accordance with EN60335-2-80. Motors are wound for 230V/1Ph/50Hz/60Hz supply. Electrical connections are made by an IP54 terminal box fitted to the outside of the fan casing.


All impellers are single inlet backward curved centrifugal type. Impellers are balanced to ISO 14694 Grade G6.3.

Quality Management

Units are to be designed and manufactured with procedures as defined in BS EN ISO 9001:2008. All HIT units are to be tested to ISO 5801:2007 (airside performance) and BS 848 Part 2:1985 (sound performance).
