Stainless Foam Oil Fume Filter

Our Stainless Foam Oil Fume Filter is designed for kitchen exhaust and oil fume pre-filtration systems where grease-laden air needs to be intercepted before it enters the exhaust duct, fan or downstream purification equipment.

Unlike a simple flat mesh filter, this product uses a porous metal foam structure. The open-cell metal surface provides a larger contact area for oil mist and grease particles, while still allowing air to pass through the filter panel.

The filter can be supplied as a framed panel with stainless steel border and welded handles, or as porous metal foam media for customers who need to process it into their own filter structure.

This product is mainly used in commercial kitchens, restaurant exhaust hoods, hotel kitchens, central kitchens, food processing exhaust systems and oil fume pre-treatment equipment.

A kitchen exhaust system normally deals with heat, oil mist, grease, moisture and cleaning chemicals. A filter used in this position must be easy to remove, stable in shape and suitable for repeated maintenance.

•This metal foam oil fume filter is selected when the buyer needs:

•A metal filter panel for kitchen exhaust pre-filtration

•Larger oil mist contact area than simple flat mesh

•Stainless steel frame and welded handle options

•Custom panel size for existing hood or purifier equipment

A washable and reusable metal structure, subject to site cleaning practice

Pre-filtration before fan, duct, electrostatic purifier or other oil fume treatment equipment

The actual oil fume removal performance depends on foam material, pore density, thickness, airflow, installation position and cleaning condition.

A typical framed metal foam grease filter may include:

•Porous metal foam filter media

•Stainless steel outer frame

•Welded handle for easy removal

•Optional support mesh or honeycomb layer

•Custom thickness according to equipment space

•Custom size according to hood or purifier slot

For replacement projects, we can produce according to old filter samples, drawings or installation photos.

This metal foam oil fume filter can be used in:

•Restaurant kitchen exhaust hoods

•Hotel and commercial kitchen ventilation

•Central kitchen exhaust systems

•Food processing oil fume pre-filtration

•Cooking fume purifier inlet protection

•Exhaust fan and duct pre-protection

•Grease interception before downstream purification equipment

It is not intended to replace activated carbon filters for odor adsorption or HEPA filters for fine particulate cleanroom filtration.

In a kitchen exhaust system, oil fume normally passes through several stages before discharge or further purification.

A typical arrangement may be:

Cooking area → hood filter section → metal foam oil fume filter → fan / duct / oil fume purifier

The porous metal foam layer helps intercept part of the oil mist and grease particles. This can reduce grease carry-over into the duct and downstream equipment when the filter is correctly installed and maintained.

For heavy-duty cooking environments, the final system should still be designed according to local fire safety, exhaust volume, grease load and cleaning requirements.

Before installation, confirm the filter size, airflow direction, frame fit and handle position.

Recommended checks include:

•Confirm the outer size of the filter panel.

•Check whether the filter fits the hood or equipment slot.

•Make sure there is no large bypass gap around the frame.

•Install the filter in the correct position before the fan or purification section.

•Remove and clean the filter according to grease loading and site maintenance schedule.

•Avoid using cleaning methods that may damage the frame, handle or foam structure.

•Replace the filter if the foam layer is deformed, damaged, blocked or no longer cleanable.

Cleaning frequency should be decided by cooking load, operating hours, grease type and local maintenance rules.

To quote correctly, please provide:

•Filter size: width × height × thickness

•Quantity for each size

•Frame material requirement

•Foam media requirement, if specified

•Pore density or old sample, if available

•Whether handle is required

•Installation position

•Airflow or equipment model, if available

•Required documents or test reports

•Destination country and shipping term

•Photos or drawings of the existing filter

If you are not sure about the material or pore density, send us clear photos of the current filter and the installation slot. We can help check the basic replacement direction.
