The RELY FX™ P20PKP-HF PKP dry chemical fire extinguisher is designed to effectively suppress Class B and C fires for both novice and professional operators. It is ideally suited for deployment in demanding environments including emergency response, military applications, and corrosive marine conditions.
Constructed with a non-shat DOT 3AL-1800 aluminum cylinder, the unit has successfully passed rigorous vibration and shock testing generating impact forces up to 200 Gs to ensure structural and operational integrity under severe conditions. This durable design supports reliable deployment where high-output fire suppression is critical.
The P20PKP-HF model carries a 10-year limited factory warranty and is manufacturer-tested for operational performance across temperature extremes ranging from -65°F to 160°F, supporting a total functional temperature span of 225°F.
What is a PKP fire extinguisher used for?
PKP fire extinguishers are designed for Class B and C fires, particularly flammable liquid hazards in industrial, aviation, marine, and fuel-handling environments.
What makes this a high-flow extinguisher?
The P20PKP-HF delivers agent at more than 1 pound per second, enabling faster fire knockdown and improved performance in complex or high-intensity fire scenarios.
What does High Hazard occupancy mean?
High Hazard environments involve greater fire risk due to higher fuel loads or more severe fire conditions, requiring higher-rated extinguishers like 80-B:C models.
Is this suitable for marine and military use?
Yes. The P20PKP-HF meets USCG requirements and aligns with DOD and Navy specifications for regulated environments.
Does this require frequent maintenance?
No. The design supports a 10-year DOT retest cycle and eliminates the need for standard 6-year internal examinations.
