Product design & filter testing


One of the benefits to manufacturing is we have the capacity to design and test bespoke products for customers. With our own CAD drawing package we can produce solutions to customer’s problems; an example of this is for Air Conditioning units.

Easy Air Conditioning of Birmingham required a solution to filter air to G3 for a range of units they install but the manufacturer of the air conditioning unit could not provide this. After an initial consultation we were able to provide prototype Side Withdrawal Frames with side access panels and replaceable G3 Filters within 1 week with a full scale production batches ready within 2 weeks.

Nearly all of our products are made with machinery that is CNC controlled; therefore quality control is never compromised.

If you have a problem that requires a solution then please contact our technical team who can discuss your requirements either on +44 1264 332993 or by email
