BA450EX Zone 1 Breathing-Air Compressor for hire
The Factair BA450EX is a electrically powered, breathing-air compressor designed to operate in a hazardous area (designated Zone I Equipment Group II, category 2 G (IIB T4), it has a fully integrated automatic fail-safe emergency air reserve and alarm system.
In the event a drop in the primary air pressure an audible alarm will be activated and the air will continue be supplied from two 9-litre 200 bar cylinders (optional 300 bar also available). The control panel has a status indicator which in the event of a failure of the primary air will automatically change from green to red. If the air pressure in the HP cylinders drops below 140 barthis will also activate the alarm and status indicator on the control panel.
It incorporates a Gardner Denver Hydrovane rotary vane compressor powered by a 5.5kW, 400/480V, 50/60Hz three phase explosion proof electric motor c/w a DOL starter.
The compressed air generated is passed through a fan assisted aftercooler before proceeding through a multi-stage filtration system which removes particulates, reduces oil contamination to <0.003 parts per million and also removes hydrocarbon vapours. The air is then passed through a membrane dryer to ensure a 5°C suppression of dewpoint in ambient temperatures >0°C with air quality exceeding the criteria laid down in BS EN12021. Breathing Air is then supplied to 2 flow protected Draeger/Scott compatible outlets.
