فلتر مياه عالي التدفق من الفولاذ المقاوم للصدأ

• High temperature duty: above the ceiling of a polymer element.
• Cleanable service: where the element is cleaned rather than replaced.
• High pressure systems: where element and housing share the load.
• Industrial water: high flow prefiltration.

Three conditions justify the cost. Anything else and a polymer element does the same job for less.

• Working temperature above roughly 120 °C. Past that, polyester and glass fibre constructions are out and metal is the remaining option.
• The element is cleaned, not replaced. Where a change-out means opening a contained system, an element that can be backwashed or chemically cleaned in place changes the operating model rather than just the consumable cost.
• Element and housing share the pressure. Some high pressure arrangements load the element directly, and a polymer pack will deform where a metal one will not.

Durability on its own is not a reason. A stainless element on ordinary ambient water duty is capital spent to solve a problem the application does not have.

This series is configured against the duty rather than picked from a table, so the enquiry carries more weight than usual. Send:

• The fluid, its concentration and its working temperature
• Flow rate and the differential pressure available
• Required micron grade
• Housing make and model, or the dimensional envelope
• Whether the element will be cleaned in service, and by what method
• Any code or material certification the site requires

Pullner issues the full specification against those conditions, including dimensions, fittings, pressure and temperature limits. Where an existing element is being replaced, a photograph of it and its seating face shortens the exchange considerably.
