ABOUT US Oxford Filtration Ltd is a market leading manufacturer of simplex and duplex basket strainers and self clean filters and other fluid straining equipment. Founded in 2000 our reputation is based on the innovation of our product design within the filtration industry. Our products are seen in many of the largest companies worldwide often serviced by a local representative. We operate from our manufacturing facility in Windsor in the U.K. (conveniently close to Heathrow) which has a full machining facility. We have a technical sales team in the UK at your disposal. We also have major international distributors in the U.S.A., Singapore, Malaysia, Australia, Spain, Finland, Italy and South Africa who stock our products. In addition we have local representation in Mexico, Brazil, Canada, Norway and New Zealand. We stock most standard strainer products in cast iron, carbon and stainless steel and in most pipeline sizes with ANSI and DIN flanges and screwed BSP and NPT offered. We offer higher pressure designs to demand and also other materials which are often not routinely stocked such as bronze and hastelloy. Our design team can offer designs to customer bespoke requirements encompassing pressure vessel standards such as PD5500, ASME 8 and EN-13445. Our on site metallurgist deals routinely with all material queries on castings and fabrication work, and material and test certificates are naturally routinely available. Programmes are available on this site developed in house by our engineers to provide quick calculations of pressure drops on our strainers from basic process data. Disclaimer It is the policy of Oxford Filtration to continuously improve our products. The right is reserved to amend specifications and products without prior notice. We offer our products strictly in accordance with our terms and2 conditions available on request.

SIMPLEX BASKET STRAINERSApplicationOxford Filtration Model XS Series simplex strainers provide a simplecost-effective way to separate particle impurities from fluid flow systems.Simplex models described in this brochure are designed for applicationswhere temporary interruption of a batch process can be permitted forbasket cleaning. Where continuous, uninterrupted flow is required, ourduplex strainers or self cleaning filters described on pages 7 and 9 ofthis brochure should be used. All strainers are individually pressure tested.• Available in cast iron, bronze, carbon and stainless steel and other materials to customer order.• Pipeline sizes from 20mm (3/4”) to 450mm (18”) (ask for details of sizes above 200mm (8”) ).• Available flanged in all common drillings including PN16 and ANSI150 (ANSI300 and 600 on request) and screwed ports both BSP and NPT or socket weld.• XS range with PN16 drilling up to 16 BarG*• XS steel range with ANSI150 drilling up to 19BarG* (cast iron ANSI125 limited to 13.8 BarG*).• Large filter basket areas and manufactured in st. steel 316.• 100% full flow.• Extended area basket available.• Various options including differential pressure indicator, magnets to 3 remove ferrous particles, heating jackets.(*Note – pressures quoted at 50C max. Pressures will reduce with higher temperatures and are limited to flange rating. Temperature limited by seal selection)

DUPLEX BASKET STRAINERSApplicationDuplex Basket Strainers are designed for applications where continuous flowmust be maintained whilst cleaning filter baskets. The strainer uses integral 3 waystainless steel ball valves with PTFE seals. This design provides drop tight shutoffeliminating costly and potentially dangerous leakage into the chamber not in usewhich can occur in some other duplex strainer designs. This also eliminates someproblems which can occur in particular suction conditions where in other designsair ingress could occur. All parts of the valve mechanism are accessible afterremoving the basket chamber without taking the strainer out of the pipeline.The handle covers the strainer chamber when in use and prevents accidentalopening of the filter cover.• Available in cast iron, bronze, carbon and stainless steel.• Pipeline sizes from 20mm (3/4”) to 200mm (8”) (ask for details of sizes above 200mm).• Available flanged in all common drillings including PN16 and ANSI150 (ANSI300 and 600 on request) and screwed ports both BSP and NPT or socket weld.• XD range up to 13.8 Barg (pressure stated at 50C, lower pressure at higher temperatures, ask if unsure). Temperature limited by chosen seal. Pressure also limited by flange rating.• Large filter baskets areas, manufactured in st. steel 316.• Various options including differential pressure indicator, magnets and heating jackets.• Can be coated internally and externally. 7

SELF-CLEAN FILTERS Benefits of Self-Clean Filters • Provides an efficient filtration solution for virtually any fluid with viscosity from a thick viscous resin and adhesive to water. • Element cleaning without interrupting flow or losing system pres- sure or any fluid loss. • Fully enclosed system with no operator contact with the fluid therefore ideal for hazardous or sensitive applications and also no chance of externally introduced contamination into the product. • Cleaner and safer operating area. • Manual or fully automated operation. • Reduces labour cost associated with more traditional filtering methods such as strainers and bag filters and also minimises any production down time. 9
