Beko Condensate Systems Ltd h a s introduced two new products to t h e UK m a r k e t in t h e field of compressor condensate m a n a g e m e n t . These are a n addition to its O w a m a t range of oil/water separators, and a new Bekosplit unit designed to s e p a r a t e heavily emulsified condensate. The new Owamat 2 is well suited for compressors u p to 15 h p a n d will therefore offer advantages to users in fields o t h e r t h a n t h o s e associated with t h e larger stablemates, Owamat 4 a n d 6. This latest addition to t h e r a n g e will be of equal import a n c e to small m a n u f a c t u r i n g companies, garages a n d o t h e r users.

T h e Safe Lock S y s t e m w o r k s like a c o n v e n t i o n a l safe door. As t h e h a n d l e is t u r n e d in a clockwise direction, six stainless-steel feet close down on t h e pressure vessel. Once t h e h a n d l e is fully depressed in t h e closed position, t h e vessel is sealed a n d operational. In t h e s t a n d a r d version t h e m a x i m u m pressure r a t i n g is 10 bar, b u t modified units can be built u p to 400 b a r in mild-steel, stainless-steel, Hastelloy a n d titanium.

Dustcheck halves space demands A r a n g e of h i g h - d u t y d u s t collectors t h a t halve t h e floor space required for a given filtration rating has been i n t r o d u c e d by Dustcheck Limited. The space saving s t e m s from a configuration of cartridge e l e m e n t s installed one a b o v e t h e o t h e r vertically, instead of side-by-side. The c o m p a n y claims t h a t typically t h i s a r r a n g e m e n t enables 10,000m 3 of air to be filtered at 1 m a / m i n by a dust collector 2410 m m wide, 1550 m m deep a n d 4000 m m high. Users can either increase filtration capacity of a fixed site or reduce the space needed for a fixed capacity. D u s t c h e c k ' s new SDV/W series c o n t a i n s t e n singlea n d double-cell models r a t e d for duties from 2700 m a / h r 602
(with a filter a r e a of 45 m 2) to 23,040 m 3 / h r (with a filter a r e a of 384 m2). Both lownoise a n d s t a n d a r d versions are available. All are selfcontained units complete with filter elements, cleaning systems, fan, silencer, a n d collection bin. They can be provided factory assembled or in knocked-down form for site assembly by the user, a f u r t h e r saving o n first cost. The filtration system incorporates t h e company's latest cartridge filter elements, which have re-usable m e t a l components and simple t h r e e - p o i n t location for quick r e p l a c e m e n t a n d sealing. Installed in c o m b i n a t i o n s of 7.5, 10, 13 a n d 16 m 2 filter areas, t h e elements can be provided with various media,
