The new unit is more compact yet has a greater air output without any increase in energy consumption, and incorporates reconfiguration of the previous model’s internals, resulting in enhanced air flow to give 10% greater output (2.75 psig) with a reduction in overall size. The new model, according to the supplier, is safe and economical to run, because it delivers a high volume of air at low pressure it can be used even against exposed skin-which can be dangerous with high-pressure compressed air. The standard hose length on the wall-mounted unit is 142 cm (56 in.), with noise levels below 78 db(A). A spare filter is included with each new unit, and filter access is now easier. The JetBlack outlet nozzle can be fitted with an optional chip guard.
