AF45 550-Micron Filter Screen – BZ SUN
Best for: kitchens needing robust debris capture in high-traffic fry operations. This 13.75″ x 13.75″ straight-edge filter uses a 550-micron stainless steel mesh to trap particles before they reach the fry oil, helping maintain clarity and extend oil life. It is compatible with a variety of commercial fryers including Avantco FF300 and several Pitco and Sierra models. Choose this if you want reliable, straightforward filtration with strong debris interception.
Why selected: The 550-micron mesh provides a reliable balance between capturing medium to large particles and allowing efficient oil flow. The 304 stainless steel construction supports heavy daily use and resists corrosion. Best for: busy kitchens that prioritize oil cleanliness and consistent fry quality.
Caution: Verify fryer bottom dimensions before purchase to ensure a proper fit, as straight-edge designs require matching fryer geometries.
AF45 Thermometer Filter – Boildut
Best for: kitchens that require precise, on-the-fly temperature monitoring during frying. This filter features a built-in handle-compatible thermometer with a stainless steel stem and a wide 0°–280°C (0°–536°F) range. It helps operators achieve consistent results for items like chicken and fries by providing clear diagnostic readings without extra equipment.
Why selected: Temperature monitoring is integral to consistent fry quality. The thermometer’s clear dial and dual units simplify cooking decisions in fast-paced service. Best for: menus where precise oil temperature management matters for texture and color.
Caution: This filter uses a straight-edge design; confirm your fryer bottom is compatible (straight vs. angled) before purchasing.
Replacement AF45/TK45 – Fystensk
Best for: operators seeking enhanced oil life and food quality through a dual-filter approach. This model employs a double-layer 500-micron mesh to trap fine particles, extending oil life by up to 40% and improving fry quality. It fits a broad range of brands, including Pitco, Vulcan, Globe, and American Range, among others.
Why selected: The dual-layer design plus upgraded mounting hardware reduces filter loosening during use, which is common in busy kitchens. Best for: high-volume operations needing reliable, long-lasting filtration with fewer interruptions.
Caution: Confirm fryer bottom size is within the 13.75″ x 13.75″ footprint and ensure straight-edge compatibility with your fryer model.
AF45 Oil Filter Strainer – Hohnezl
Best for: operations needing broad compatibility with Pitco, Avantco, American Range, and more. This 13.75″ x 13.75″ straight-edge filter uses a 550-micron mesh to trap debris and extend oil life by up to 40%, maintaining crisp, consistent fried foods.
Why selected: It offers strong cross-brand compatibility and a straightforward straight-edge design that simplifies installation. Best for: kitchens seeking a durable, all-purpose fryer filter with predictable performance.
Caution: Not suitable for fryers requiring beveled or angled edge filters; verify edge design with your fryer model before ordering.

Best for: teams prioritizing safety with heavy-duty filtration. This SR142GN model features a 360° laser-rolled safety edge to prevent burr injuries, plus a dual-layer 500-micron mesh for dual-stage filtration that captures large debris and micro-carbon particles.
Why selected: The quick-lift dual-handles speed routine clean-outs, a critical advantage in high-volume environments. Best for: kitchens requiring efficient, safer handling and strong filtration performance.
Caution: Ensure compatibility with Dean, Pitco, Avantco, Sierra, and similar models by checking dimensions and edge requirements.
Buying Guide
What to consider when choosing a commercial fryer filter
- Filter mesh size: Larger microns trap bigger debris but may reduce filtration efficiency for fine particles. A 500–550 micron range balances debris capture with oil flow.
- Edge design: Straight-edge filters suit fryers with flat bottoms; beveled/angled edge filters require specific fryer geometries. Always verify edge shape before purchase.
- Compatibility: Check model and brand compatibility, confirming bottom dimensions and model numbers to avoid mismatches in busy kitchens.
- Oil-life impact: Some filters advertise up to 40% oil-life extension. Consider whether your operation values oil longevity, cost efficiency, or both.
- Additional features: Thermometer-integrated filters aid temperature control; safety-edged designs reduce staff injury risk during handling.
How to compare options quickly
- Match your fryer brand and model list against the filter’s compatibility notes.
- Assess whether you need a straight-edge filter or a filter with built-in measurement features like a thermometer.
- Estimate oil-life benefits by considering your current oil turnaround and waste levels.
- Consider handling convenience, such as quick-lift handles and durable construction.
Practical questions to ask before buying
- Is my fryer bottom straight or angled, and does the filter require a specific edge?
- What oil-life improvement should I expect in my kitchen’s daily volume?
- Do I need an integrated thermometer or just a basic filtration screen?
- Will the filter fit within the fryer’s cold zone without bypassing filtration?
Maintenance tips
- Regularly inspect the mesh for tears or clogging; replace when debris reduces filtration efficiency.
- Rinse filters with warm water after use and allow to dry completely before reinstalling.
- When using dual-filter designs, pair with pre-filter papers if recommended by the manufacturer for best results.
