The ‘City Filter’ will, it is claimed, make trucks and buses practically free of smell and smoke, and it is said not to tiave a negative effect on engine power output or fuel consumption. Noise levels are also claimed to be reduced. The filter is said to have a service life of about 300,OOOkm and is fitted in the exhaust system. Emissions from the engine are led into a container and forced to pass through a ceramic filter with a catalytic covering of precious metal. The filter lasts for operations up to 350km and a lamp on the dashboard indicates when it is close to the limit. Overnight, an electric element at the bottom of the filter is connected to a 22OV point for purification. Cornbustion takes about three hours and gives mainly harmless residual products. The process can safely be performed indoors, it is stated.

Airoil Flaregas has recently commissioned a test firing rig. Built at a cost of f%m. the rig complemented by state-ofFiltration &Separation
the-art sampling equipment for NOx, CO, oxygen and particulates, is designed to work with a wide range of liquid and gaseous fuels including heavy fuel oil, diesel oil, naptha, natural gas, hydrogen, propane and nitrogen. Mexinsum capacity is 9MW. Airoil-Flaregas, PO Box 92, Horton Road, West Drayton, MiddleBex, U67 8BG.

A new division has been set up by DPE to co-ordinate and expand its dust extraction activities in the general industrial sector, in addition to the timber and wood processing industries. Dust and fume control products developed include environmental booths and sanding benches, and the Filtajet range of reverse pulse duSt collectors. The company specialises in turnkey projects. Heading the new division’s sales force are Mick Kellett, who has been with DPE for and Graham three years, Rttiiiy. who has been a senior member of the Filtajet technical staff for IO years. DfE Ltd.
