FF0'-'-0'N° the introduction, last year, of the Mopal compressor, the Overseas Engineering Co., Ltd., 200, Bishopsgate, London, E.C.2, received many requests from transport operators at home and overseas for a larger model more suitable for application to commercial vehicles.
This demand has been met by the production of a larger compressor, the M.0.4, which retails at £15 10s. Its capacity is 21 cubic ft. of free air per min. at 1,000 r.p.m. and it can, if necessary, be operated to give a maximum pressure of 120 lb. per sq. in.
The compressor is designed to fit on the dynamo of an engine, provided that a drive can be taken from the rotatingshaft pulley. The driving belt, when not in use, can be carried in the base of the unit, the top folding back to allow it to be placed inside. The holding
catch is threaded and this provides a simple means for keeping the correct tension on the belt so that adjustment may be made for belt tension.
The bearings and the bore are impregnated with alcohol and graphite, and are thus self-lubricating. Additional lubrication of the bore is provided by means of a small oil filler which feeds through a wick.
The M.0.4 is supplied complete with 30 ft. of air line, a pressure gauge and a valve connector.
The equipment should be particularly useful overseas for inflating tyrts which deflate rapidly after running on hot roads. The unit can also be applied to operate small power tools and sprayers. At home, it may appeal to small operators who have no pneumatic installations, but are seeking suitable equipment at low cost.
