Iron-Nickel Foam Oil Mist Filter A1 20 PPI ATOMFAIR®

METAL POROUS PLATE OIL FILTER IRON NICKEL FOAM 93% INTERCEPTION

RESEARCH GRADE MATERIAL

Product Overview

This Metal Porous Plate Oil Filter integrates a high-performance iron nickel foam 93% interception rate core within a robust metal frame to deliver sub-high-efficiency oil mist separation for industrial and commercial exhaust systems. The 3D gradient honeycomb metal structure employs physical oil mist coalescing filtration—forcing aerosolized oil particles through continuous directional collisions that capture and coalesce droplets onto the filter matrix. A proprietary nano-metal coating imparts oleophobic surface properties, enabling captured grease to drain passively into collection channels. Engineered as an A1 fire rated acid-alkali resistant solution, the all-metal construction withstands operating temperatures up to 1450°C (melting point) while resisting chemical degradation from aggressive exhaust condensates and cleaning agents, ensuring permanent compliance with fire safety and emission standards.

Key Features & Advantages

93% Particulate Interception with Passive Physical Filtration: The 3D gradient honeycomb metal structure forces aerosolized oil particles to undergo continuous directional changes, maximizing inertial impaction and coalescence without consuming electrical energy, achieving verified interception rates exceeding 93% for sustainable emission compliance.
A1 Fire-Rated Non-Combustible Construction: Fabricated entirely from iron-nickel foam and metal frame materials with a melting point of 1450°C, the filter achieves A1 fire classification, effectively eliminating duct fire hazards in commercial kitchen and industrial exhaust systems.
Oleophobic Nano-Metal Coating for Self-Drainage: The proprietary nano-scale surface treatment renders the filter non-stick to oil, enabling captured grease to drain passively along guide channels into collection trays, preventing filter saturation and maintaining consistent low wind resistance below 100 Pa.
80% Reduction in Duct Cleaning Costs: By intercepting over 93% of particulate matter before it enters the exhaust ductwork, this filter reduces annual duct cleaning frequency and associated operational expenditure by more than 80%, while extending the service life of downstream exhaust and ventilation equipment.

APPLICATION SCOPE: Designed for machining oil mist purification systems, heat treatment quenching smoke abatement, die-casting and injection molding workshop air purification, and pre-filtration stages in commercial kitchen exhaust hoods. Compatible with HVAC systems, automotive engine intake filtration, sugar processing, fuel tank venting, paint spray booth exhaust, and water filtration basins. The filter operates on the principle of physical oil mist coalescing filtration, suitable for air conditioning, automotive engine systems, industrial filters, range hoods, and filtration kettles where A1 fire-rated non-combustible media is required by code.

PACKAGING: Standard configurations available in 500 × 500 mm, 500 × 600 mm, and 200 × 300 mm plate sizes with 10 mm or 15 mm thickness and 20 PPI pore density. Custom dimensions, thicknesses (1–30 mm), and PPI grades (5–500 PPI) manufactured to order. Frame material options include galvanized steel, natural aluminum, and stainless steel with protective mesh choices of woven screen, diamond mesh, or perforated plate. Each filter is individually packed with edge protection to prevent frame deformation during transit.

IMPORTANT NOTICE: Routine cleaning is accomplished by direct water jet washing; the all-metal A1 fire-rated construction permits aggressive mechanical cleaning without degradation. While the iron-nickel foam core and stainless steel frame are inherently acid-alkali resistant, avoid prolonged immersion in concentrated hydrochloric acid (pH < 1) to preserve the nano-metal oleophobic coating integrity. For optimal physical oil mist coalescing filtration performance, clean the filter when pressure differential exceeds 150 Pa or visible grease accumulation covers more than 50% of the frontal surface area. After cleaning, ensure complete drainage before reinstallation to maintain the specified wind resistance below 100 Pa. This product employs purely physical purification principles—no electrical power is consumed during operation.

How does the 3D gradient honeycomb structure balance high oil interception rate (>93%) against low wind resistance (<100 Pa)?

The inertial impaction mechanism forces aerosolized oil particles through continuous directional changes within the 3D gradient honeycomb structure, maximizing coalescence onto the iron-nickel foam matrix. With open porosity exceeding 98% and standard pore density of 20 PPI, the filter maintains wind resistance below 100 Pa while achieving an interception rate above 93%, as specified. The oleophobic nano-metal coating prevents oil saturation, preserving the low pressure drop over time without consuming electrical energy.

Can this iron-nickel foam oil filter be integrated into paint spray booth exhaust systems containing solvent-laden air?

Yes, the filter is explicitly listed as compatible with paint spray booth exhaust and similar fume extraction applications. Its all-metal construction with iron-nickel foam core and stainless steel frame provides inherent acid-alkali resistance, allowing operation in solvent-laden environments. However, the proprietary nano-metal oleophobic coating can be degraded by prolonged immersion in concentrated hydrochloric acid below pH 1, so such exposure must be avoided during cleaning or operation.

What is the recommended cleaning procedure to preserve the oleophobic coating and A1 fire rating of the iron-nickel foam filter?

Routine cleaning is performed by direct water jet washing; the A1 fire-rated all-metal construction permits aggressive mechanical cleaning without degradation. To maintain the nano-metal oleophobic coating, avoid prolonged immersion in concentrated hydrochloric acid below pH 1. Filters should be cleaned when pressure differential exceeds 150 Pa or visible grease accumulation covers more than 50% of the frontal surface area, and complete drainage before reinstallation is required to sustain wind resistance below 100 Pa.

Assessment

This iron-nickel foam oil filter achieves 93% interception via inertial impaction with a passive, A1 fire-rated metal construction. Operationally, it requires periodic water jet cleaning and must avoid prolonged immersion in strong acids to preserve the oleophobic coating.

Positive

93% Passive Particulate Interception: The 3D gradient honeycomb structure forces oil droplets through inertial impaction and coalescence without consuming electrical energy, achieving verified capture rates above 93% for sustainable emission compliance.
A1 Fire-Rated Non-Combustible Construction: All-metal iron-nickel foam and frame construction with a melting point of 1450°C achieves A1 fire classification, eliminating duct fire hazards in exhaust systems and withstanding aggressive cleaning without degradation.

Trade-offs

Acid Sensitivity of Nano-Coating: Prolonged immersion in concentrated hydrochloric acid (pH < 1) must be avoided to preserve the proprietary nano-metal oleophobic coating integrity, which is critical for passive self-drainage performance.
Drainage Requirement After Cleaning: After water jet cleaning, the filter must be completely drained before reinstallation to maintain the specified wind resistance below 100 Pa, adding a procedural step during maintenance.
