A RANGE of four commercial and domestic air jacks from Polstar Engineering have been designed to provide a simple means of jacking up any vehicle from a small car to a 10 tonne (9.84 ton) lorry. The air jack is connected to the vehicle's exhaust, blows up a very strong bag into an air cushion, so jacking up the vehicle.
Polstar say air jacks are safe and stable and have a long and successful military history. By doing away with equipment such as air bottles, gauges and so on, the air jack is now suitable for consumer and commercial use.
The exhaust gases are blown into the air jack through a hose fitted with a one-way valve so that no gas can escape. The hose is fitted to the exhaust with a "Neoprene" fitting which is simply pushed on and twisted to locate. The jack is lowered by a control arm.
Polstar says the air sack is made from high grade polyester canvas coated on both sides with PVC. There are four sizes from 500 to 820mm (19.7 to 32.3in) which can lift vehicles up to 2.5 and 10.0 tonne (2.46 and 9.84 ton) respectively.
The Polstar range of air jacks have suggested retail prices from £19.90 to £80.00 both, plus vat.
