GHF-1 explosion-proof fire-resistant breather capOverview

The GHF-1 explosion-proof flame arrestor vent cap is a explosion-proof flame arresting venting device installed on the vent ports of small tanks, fuel oil tanks, or pipeline vents. It features a built-in stainless steel corrugated plate flame arrestor element, allowing free gas breathing due to pressure changes while effectively preventing external flame ingress and backfire explosions. The housing adopts an explosion-proof design, with a rain cover and insect screen on top. Its core purpose is to provide combined explosion-proof, flame arrestor, and atmospheric venting functions for gas station underground tanks, generator fuel tanks, small oil tanks, chemical solvent drums, and day tanks, ensuring tank pressure balance and fire safety.

GHF-1 explosion-proof fire-resistant breather capCharacteristic

1. Integrated explosion-proof and flame arresting: Built-in stainless steel corrugated plate flame arrestor element effectively quenches external flames while meeting installation requirements in hazardous areas.

2. Complete breathing function: Allows free gas flow in/out due to temperature changes or liquid transfer, maintaining atmospheric pressure and preventing overpressure or vacuum.

3. Explosion-proof housing design: Made of aluminum alloy or cast steel with high structural strength to withstand accidental impact, suitable for flammable and explosive environments.

4. Complete protection structure: Top rain cover, insect screen, and internal drainage prevent rain, dust, and insects from entering, suitable for outdoor installation.

5. Flexible connection: Available with pipe threads (NPT, G, R) or flanged connections for direct screwing onto vent ports, easy installation.

6. Corrosion-resistant options: Housing available in aluminum alloy (lightweight weather-resistant), cast steel (high pressure), or stainless steel (highly corrosive environments) to suit various conditions.

7. Easy maintenance: Removable flame arrestor element for cleaning; periodic carbon deposit removal allows reuse without complete replacement.

8. Compliant with standards: Designed and manufactured according to GB 5908, ISO 16852, and other standards, with explosion-proof certification.
