required. Designed for use with two compressed air cylinders of
up to 300 bar charging pressure, supplying one or two breathing apparatus wearers, the AST unit features a control panel with reducing valve, fitted with high and medium pressure gauges and warning units. The
flexible, high pressure cylinder connection hoses incorporate a non-return valve system allowing cylinder replacement without interrupting air supply. The cylinders are held in place with an adjustable cylinder band
allowing the use of cylinders of various diameters. The RAL hose reel unit has a low friction bearing to allow for easy run out of hose and has capacity for up to 90 metres of 10 mm (3/8”) bore hose. RAL has a
manifold for connection to a factory airline supply and to the AST unit. Both ASTRAL and RAL units can be fitted with airline filter units if required.
