Hilomast Compressors - NC1 Compressor

The NC1 compressors are the smallest and simplest in the Hilomast range. They are portable and thus very suitable for field applications. The units are supplied complete with a single hose and mast connector. The mast is retracted by a manual exhaust valve on the front of the unit so enabling full control from inside a vehicle or building. Although designed primarily for the NH and NK Series masts they will perform perfectly satisfactorily with the NL Series, when the speed of extension is not important (See table). A remote control is available as an optional extra.

NC2 Compressor

The NC2 compressors have all the features of the NC1 compressors and give approximately twice the output. An additional feature is a single switch that controls both power supply and an electrically operated exhaust valve. This "three position" switch will (1) extend the mast or (2) hold mast at any height or (3) retract mast. The units are supplied with two hoses, one for connection to mast and one for exhaust air and drainage. This feature is very useful for vehicle installation as it drains the moisture collected in the mast from the compressor. The NC2 compressors are ideally suited for the NL Series masts but will work equally well with the NK and NX Series (see table) A remote control is available as an optional extra.

NC3 Compressor

The NC3 compressors are the largest in the Hilomast range. Although designed for NX and NY Series masts, they can be used to operate smaller masts where a faster rate of extension is required (see table) They have the same type of switch and hose arrangement as the NC2 compressors. The units are supplied to meet standard conditions, but there is capacity within the system to accommodate customers specialised electrical or pneumatic control requirements. Remote controls are available as an optional extra.

Mast Extension Rates

Hilomast Remote Controls RC1

This "three position" switch is for the remote control of NC2 and NC3 compressors. It enables the mast to be extended, retracted or held at any height. It may be hand held for DC powered compressors or mounted onto the vehicle instrument panel for both AC and DC powered units. The switch is fitted into an ABS enclosure and supplied complete with 4 metres of cable and a weatherproof plug and socket. It activates a relay and a solenoid operated air valve inside the compressor. These switches should be ordered with the compressor but can be supplied in kit form for retro-fitting to non-remote units.

Hilomast Remote Controls RC2

This "three button" relay interfaced unit has separate commands to extend, hold or retract mast. The push buttons are fitted into die cast housing with an environment protection rating of IP65 and supplied complete with 4 metres of cable and a weatherproof plug and socket. Primarily designed for external low voltage DC control of NC2 and NC3 AC driven compressors but may be used to control a relay interface for DC driven compressors. These remote controls must be ordered with the compressor.
