KNOKOO-Spark Arrestor Filter Grid

I. Product Overview

The Spark Arrestor Filter Grid is a critical protective filtration component specifically designed to intercept sparks, molten metal splatter, and high-temperature particles carried in airflow. Manufactured from high-temperature-resistant, flame-retardant materials and featuring a multi-layer composite structure, it effectively blocks spark transmission and prevents ignition of downstream equipment or filter media.

By eliminating fire hazards at the source and pre-capturing large, high-temperature particulates, the filter grid significantly reduces the load on downstream filtration systems and extends their service life. It is an indispensable safety barrier in industrial ventilation and dust collection systems.

II. Core Materials & Manufacturing Technology

• Multi-Layer Metal Mesh
  Constructed from stainless steel or heat-resistant alloy wire, the mesh density is precisely optimized to ensure efficient interception of sparks and hot particles while maintaining low airflow resistance, preserving normal ventilation performance.

• Fire-Resistant Barrier Layer
  Incorporates ceramic fiber or basalt fiber coatings, offering exceptional heat resistance and flame-retardant properties. The layer withstands instantaneous thermal shocks and effectively blocks spark propagation, preventing fire spread.

III. Key Performance Advantages

1. High-Efficiency Spark Interception
   Accurately captures sparks and high-temperature particles ≥0.5 mm, achieving an interception efficiency of ≥99.5%, effectively eliminating spark-induced safety risks.

2. High-Temperature & Impact Resistance
   Designed for continuous operation at temperatures up to 400°C, with short-term tolerance of peak temperatures up to 800°C. It withstands frequent thermal shocks in demanding industrial environments while maintaining structural integrity.

3. Low Maintenance & High Durability
   Supports removable cleaning, reverse airflow blow-off, or cleaning with a high-pressure water jet (pressure <0.3 MPa). After cleaning, filtration performance recovery exceeds 95%, significantly reducing maintenance costs.

IV. Installation, Maintenance & Usage Guidelines

1. Installation Requirements

• The filter grid must be installed upstream of dust collectors or fans, maintaining a minimum distance of 1.5 meters from the spark source to prevent direct high-temperature impact and ensure effective protection.

• Flange connections with sealing gaskets are required to ensure airtight installation, preventing sparks from escaping through gaps and causing safety hazards.

2. Cleaning & Maintenance

• Inspect the mesh surface monthly for clogging. Cleaning can be performed using reverse compressed air blow-off or soaking with a neutral cleaning agent to maintain airflow permeability.

• If severe deformation or damage to the filter media is observed, the unit must be replaced immediately to avoid protection failure and potential safety risks.

3. Usage Restrictions

This product must not be used in environments containing strong acidic or alkaline gases, as corrosion may compromise structural integrity and reduce protective performance.
