Structured Manufacturing Data (2026)

Filter Housing

Based on aggregated insights from structured factory profiles within the CNFX directory, the standard Filter Housing used in the Chemical Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Filter Housing is characterized by the integration of Housing Body and Closure Mechanism. In industrial production environments, manufacturers listed on CNFX commonly emphasize Stainless Steel 316L construction to support stable, high-cycle operation across diverse manufacturing scenarios.

The structural enclosure that contains and supports filter media in a filtration system.

Product Specifications

Technical details and manufacturing context for Filter Housing

Definition
A filter housing is the pressure-rated container that holds filter elements, cartridges, or bags within an automated chemical filtration and separation system. It provides structural integrity, ensures proper sealing to prevent bypass, and facilitates safe handling of process fluids under various operating conditions.
Working Principle
The housing creates a sealed chamber where contaminated fluid enters, passes through the filter media contained within, and exits as filtered fluid. It withstands system pressure, maintains flow direction, and allows for filter installation, removal, and maintenance.
Common Materials
Stainless Steel 316L, Polypropylene, Carbon Steel
Technical Parameters
  • Maximum operating pressure rating of the filter housing (inches) Standard Spec

Frequently Asked Questions

What materials are best for chemical filter housings?

Stainless Steel 316L offers excellent corrosion resistance for harsh chemicals, Polypropylene is cost-effective for moderate conditions, and Carbon Steel provides strength for high-pressure applications with proper coating.

How do I select the right filter housing volume?

Choose housing volume based on flow rate, filter media capacity, and system downtime requirements. Larger volumes extend filter life but increase footprint and cost.

Why is a pressure relief valve important in filter housings?

A pressure relief valve prevents over-pressurization from clogged filters or system surges, protecting the housing integrity and ensuring safe operation in chemical processing environments.

Can I contact factories directly on CNFX?

CNFX is an open directory, not a transaction platform. Each factory profile provides direct contact information and production details to help you initiate direct inquiries with Chinese suppliers.
