SF Series Full 316 Stainless Steel Air Filters

The SF Series is your first line of defense for protecting sensitive pneumatic components in harsh environments. As a full 316 stainless steel air filter, it is engineered to effectively remove solid particulates and condensed water from your compressed air lines. Rated for a high operating pressure up to 1.6 MPa (16 bar), the robust SS316 body and bowl construction makes it impervious to corrosion, making it the ideal choice for washdown, food grade, and chemical applications. Ensure your equipment receives clean, dry air with a filter built to withstand the toughest conditions.

Features & Key Specifications

Features & Key Specifications of Our SF Series:

Full 316 Stainless Steel Construction:

The filter body and bowl are both constructed from SS316 stainless steel, offering the highest level of resistance to corrosion from cleaning agents, chemicals, and saline environments.

High-Pressure Operation (up to 1.6 MPa):

Designed to handle demanding industrial systems, this filter operates reliably at a working pressure up to 1.6 MPa (16 bar / 232 PSI).

Efficient Water and Particulate Removal:

The internal element and baffle system effectively separates and removes contaminants. Standard models feature a 25 micron filter element, with a high-precision 5 micron element available as an option for more critical applications.

High Flow, Low Pressure Drop Design:

Engineered to provide maximum filtration without significantly impeding air flow, ensuring your tools and actuators receive the power they need to operate efficiently.

Universal Thread Options (BSPP, BSPT, NPT):

To ensure global compatibility, we offer three thread standards: G (BSPP) for most regions, P (BSPT), and T (NPT) for the North American market.

Designed for Harsh Environments:

The robust construction makes this an ideal washdown air filter. It is built to withstand the rigors of hygienic cleaning protocols and demanding industrial conditions.


Application Fields

Protecting Pneumatic Systems in Critical Industries:

Food & Beverage: Providing clean, instrument-quality air for packaging machinery, actuators, and pneumatic controls in sanitary environments.

Pharmaceutical & Biotech: A perfect food grade air filter for cleanroom applications, bioreactors, and tablet presses.

Chemical Processing: Protecting pneumatic valves and actuators from contaminated plant air in corrosive atmospheres.

Marine & Offshore: Removing moisture and salt particles from high-pressure compressed air on ships and platforms.

Paint & Finishing: Ensuring a flawless finish by removing oil, water, and dirt particles before spray guns.


Technical & Selection Guide

Why Choose a Full Stainless Steel Filter?

Superior Contaminant Resistance: In environments where the compressed air itself or the surrounding atmosphere is corrosive, a standard aluminum or polycarbonate bowl will degrade. 316 stainless steel is essential for longevity.

Washdown Compatibility: Polycarbonate bowls can crack when exposed to certain cleaning chemicals. A full stainless steel filter is completely immune to these issues, making it the only choice for serious washdown applications.

Hygienic Standards: For any food grade or pharmaceutical application, a stainless steel filter is the industry standard to ensure cleanliness and prevent contamination.

Choosing Your Filter Precision:

25 Micron (Standard): Excellent for general-purpose pneumatic applications, protecting most valves and cylinders.

5 Micron (Optional): Recommended for protecting high-precision components like pneumatic positioners, air bearings, or for instrumentation air.


FAQ

Frequently Asked questions

Q: What is the function of a compressed air filter?

A: Its main job is to remove two things from a compressed air stream: solid particles (like dust, rust, and pipe scale) and liquid water (which condenses as the air cools).

Q: What is the maximum pressure this filter can handle?

A: The maximum working pressure for the SF series is 1.6 MPa, which is equivalent to 16 bar or approximately 232 PSI.

Q: How does the water get drained from the bowl?

A: These filters are typically equipped with a manual or semi-automatic drain. A fully automatic drain option may also be available. Please check the specific model's datasheet.

Q: What is the difference between this filter and a coalescing filter?

A: This is a particulate and water separator filter, designed to remove larger particles and bulk liquids. A coalescing filter is a higher-efficiency filter used downstream to remove very fine oil aerosols.
