Stainless Steel Baffle Grease Filter

This stainless steel baffle grease filter is made for commercial kitchen exhaust hoods. Its job is to help separate grease-laden vapor before the air moves into the exhaust duct, fan or oil fume treatment equipment.

The difference is in the structure.

A mesh filter uses layers of metal mesh. A metal foam filter uses porous metal material. A baffle grease filter uses formed metal blades. When hot, grease-laden air passes through the baffle channels, the airflow changes direction. Grease droplets contact the metal surfaces, separate from the air stream and move downward toward the drainage area.

That is why this product is usually selected for kitchen hood replacement projects, restaurant exhaust systems and commercial cooking ventilation where regular removal and cleaning are part of the maintenance routine.

This filter is mainly used at the hood filter section of a commercial kitchen exhaust system.

Typical positions include:

Restaurant kitchen hoods

Hotel kitchen exhaust hoods

Central kitchen ventilation systems

Canteen and food service exhaust systems

Commercial cooking exhaust filter slots

Replacement filters for existing stainless steel hood filters

It is not an odor filter, not an activated carbon filter and not a HEPA filter. It is a grease separation filter used before the duct, fan or downstream oil fume treatment unit.

The filter is built with vertical metal baffles inside a rigid outer frame.

When cooking exhaust passes through the filter, the air is forced to turn along the baffle path. Heavier grease droplets are more likely to contact the metal surface during these direction changes. The collected grease then drains downward instead of staying suspended in the air stream.

This structure makes the filter different from flat mesh filters, which depend mainly on mesh layers to catch grease. A baffle filter is easier to rinse and inspect because the metal passages are more open and the grease path is more defined.

Actual grease separation depends on airflow, cooking load, grease particle size, filter angle, hood design and cleaning condition.

For a new buyer, this product may look simple. In real replacement work, several small details decide whether the filter fits properly.

Outer size
The width, height and thickness must match the hood filter slot.

Baffle direction
The baffles are normally installed vertically so that collected grease can drain downward.

Handle position
Side handles help workers remove the filter during cleaning. The handle position should not interfere with the hood slot.

Drainage holes
Bottom drainage holes help guide collected grease. Their position should match the way the hood manages grease.

Frame strength
The frame must stay straight after repeated removal, cleaning and installation.

Material choice
Stainless steel is commonly selected for commercial kitchen use because it handles cleaning better than many light-duty materials. The exact material grade should be confirmed when the project requires it.

 

The two products can both be used in oil fume-related systems, but they should not be described as the same filter. 

Product Structure

A typical stainless steel baffle grease filter includes:

•Outer metal frame

•Vertical baffle blades

•Side handles

•Bottom drainage holes

•Riveted or welded fixing points

•Reinforced frame option when required

The product can be made according to standard sizes or customized according to old samples, drawings or hood slot dimensions.

Some markets require listed grease filters or specific fire safety documentation for commercial cooking exhaust systems.

If your project requires UL 1046, NFPA 96, local fire approval or third-party testing, please confirm the exact requirement before ordering. We should not mark a product as "UL listed" or "NFPA compliant" unless the document matches the exact model, material and construction.

For quotation, we can provide product specifications, material information, packing details and available supporting documents according to the confirmed product scope.

Please send the following information before quotation:

•Filter width, height and thickness

•Quantity for each size

•Material requirement

•Old filter photos

•Hood slot photos, if available

•Handle position

•Drainage hole requirement

•Required documents or test reports

•Destination country and shipping term

For replacement orders, old filter photos are often more useful than a written name. A front view, side view and close-up of the handle or drainage area can help us check the structure faster.
