Grease Filters and Framed Filters

Knitwire produces a wide range of knitted mesh filter elements for industrial filtration and de-misting applications. A common use is in industrial cooking canopies, where framed grease filters are installed above cooking ranges to capture entrained grease and fat, reducing fire risk and protecting motors, blowers, and ductwork. Our knitted mesh filters are designed to provide maximum efficiency with minimal resistance, ensuring safe and effective operation in demanding industrial environments.

• Optimal Filtration Performance: Knitted wire mesh grease filters offer maximum efficiency up to 98%, with thickness, density, and wire size tailored for specific process conditions.
• Reusable Frames: Mesh pads can often be replaced while reusing the support channel frame and grid, reducing maintenance costs.
• Durable Construction: Multi-layer aluminium, galvanized, or stainless steel knitted mesh enclosed in a robust channel frame.
• Easy Handling: Frames can include handles for quick removal, cleaning, and replacement.
• Customisable Sizes: Stock sizes available, with low-cost custom dimensions easily manufactured to suit any application.

• Material Options: Aluminium, galvanized steel, stainless steel
• Construction: Multi-layer crimped knitted mesh in channel frame
• Facias: Expanded metal or welded metal front and back
• Filtration Efficiency: Up to 98%
• Pressure Drop: Optimised for low resistance and high flow capacity
• Installation: Standard or custom frame sizes, easy to remove for cleaning
• Applications: Industrial cooking canopies, extraction ducts, de-misting, and general process filtration

• Single-Layer Metal Filters: Simple and inexpensive but may have limited efficiency and higher resistance.
• Fibreglass or Paper Filters: Disposable options with lower durability and higher replacement costs.
• Knitted Mesh Filters (Knitwire): Combine high efficiency, low pressure drop, and robust construction. Frames are reusable, and multi-layer mesh design optimises flow capacity and grease capture.

• Up to 98% maximum efficiency
• Reusable frames reduce long-term costs
• Durable multi-layer mesh suitable for high-traffic kitchens or industrial environments
• Customisable sizes and materials for specific process requirements
