RCM was established in 1948 as Richard Crittal Marine, manufacturing the ‘Stylojet’ diffuser range of products, and was based in Great Portland Street, London.

In the intervening years we have developed into one of the country’s leading suppliers of air distribution equipment, with a reputation for providing the very highest quality products backed up with our second to none customer care.

Operating from our new manufacturing facility in Kempston – Bedfordshire, we can provide a full range of Bespoke Air Distribution Products as well as our Standard Product Range.


In addition to Air Grilles and Air Diffusers we can now provide Louvres, Plenum Boxes, Swirl Diffusers, Supply and Exhaust Valves.

In fact, pretty much anything you would expect from a grille and diffuser manufacturer, we can supply.

We pride ourselves on our flexibility and are more than happy to undertake special bespoke projects and as well as aluminium we can provide steel, brass, bronze, chrome and nickel coated finishes alongside an unlimited range of colours.

The team at RCM Products are fully committed to providing our customers with a first class service. Our dedication to customer service and belief in the quality of our products and brand became more evident when the company recently came under the ownership of a long standing employee.
