We offer a wide range of housings suitable for smaller process flows where a single filter cartridge is required. The high quality 50 Series housing range is supplied for smaller process flows where a single filter cartridge is required. The 51 Series is suitable for general applications and the 52 Series and 53 Series are designed for higher pressures. The 54 Series ClearView housing contains a borosilicate ‘viewing’ section to assist in process monitoring. Other products in this range include the easy access 55 Series housing and the 56 Series which utilises a high security closure.
The 60 Series is a range of light weight multi-cartridge housings suitable for general liquid and gas process applications. They are offered with a range of closure types and inlet and outlet connections. The range includes the free standing 61 Series housings and the dished end 62 Series.

The 81 Series is designed to suit mini bags for low flow / low solid applications. The 84 Series range is a free standing single bag housing and the 85 Series and 86 Series (86A and 86B) offer robust construction, which suit all areas of chemical and liquid processing plants. We also offer the 88 Series range of multi-bag housings for higher flow applications.
Amazon Filters is a leading supplier of filter housings to a wide range of industries including many where effective filtration of chemical products is critical to their operations. Where highly corrosive chemicals such as concentrated acids are being processed, specialised housings manufactured with an internal coating or made from exotic alloys such as hastelloy may be considered. Neither of these options is ideal - Coatings are prone to mechanical damage and nickel alloys have limited resistance to corrosion by acids and some other chemicals. In order to provide enhanced support to companies who have a requirement to filter highly corrosive fluids Amazon Filters is introducing two new ranges of filter housings – Tantaline Housing and 18 Series PTFE Housings. These exhibit exceptional resistance to chemical damage.
Engineering Contractors and project teams in Process Companies commonly will find an 'off the shelf' solution when looking for filtration systems. However, where the project is very large or unusual, standard products may not be suitable, therefore a bespoke system is required. Our filtration partner Amazon Filters is well placed to satisfy both of these requirements.
