PPH / PVDF Filter Housing Features

The product features below are based on the supplied Incefiltration product sheet.

One-Piece Injection Molding

The housing body is molded as one piece without welded vessel seams, helping reduce side-leakage risk.

Chemical Corrosion Resistance

PPH and PVDF material options support compatible acidic, alkaline and corrosive liquid applications.

Arched Sealing Structure

The arched structure presses the filter basket against the sealing ring to improve sealing between the basket and housing.

Easy Cover Operation

Rotating-bolt, screw-top and lifting-ring cover styles simplify installation and filter bag replacement.

Wear & Aging Resistance

Selected molded polymer construction supports compatible long-term industrial service.

FKM Sealing System

Reference O-rings are listed as FKM for the vessel, basket, inlet and outlet.

Optional Safety Switch

A micro-switch-type protection switch can be added to the model configuration.

PPH / PVDF Filter Housing FAQ

Common questions before selecting a molded non-metallic bag filter housing.

What is the main advantage of one-piece injection molding?

The molded vessel body avoids welded body seams and can reduce potential leakage paths in compatible service.

What is the difference between PPH and PVDF housings?

PPH is an economical chemical-resistant polypropylene material, while PVDF is selected for applications requiring an alternative fluoropolymer compatibility profile. Final selection requires chemical and temperature review.

Which filter bag sizes are supported?

The supplied coding lists 180 × 430, 180 × 810, 105 × 380, 150 × 510 and 180 × 560 mm bags.

What cover types are available?

The coding includes an A screw-top cover, B lifting-ring gland and AX screw-top cover with union-type inlet and outlet.

Can a pressure gauge and safety switch be added?

Yes. The code includes plugged, pressure-gauge and exhaust-valve joint options, plus an optional K micro-switch protection device.

What are the reference pressure and flow ratings?

The supplied PPH table lists 0.8 MPa maximum pressure and model reference flows from 12 to 40 m³/h.

Does the PPH performance table also apply to PVDF?

Not automatically. PVDF models require a separate confirmation of pressure, temperature, component materials and dimensional configuration.
