The Kidde Pro CD50 CDM-2 is a 50 lb wheeled carbon dioxide fire extinguisher rated 20-B:C, designed for industrial and commercial flammable liquid and electrical fires. CO2 is a clean, residue-free agent that leaves no chemical mess — ideal for server rooms, laboratories, printing facilities, and areas with sensitive electronics. The self-expelling CO2 design requires no separate propellant. Features heavy-duty hand wheel cylinder activation valves, 16-inch semi-pneumatic rubber wheels, and DOT approval. One-person operable.
What does self-expelling mean for CO2 extinguishers?
Self-expelling means the CO2 agent acts as its own propellant — the gas pressure within the cylinder drives the agent out when discharged. No separate nitrogen or dry nitrogen cartridge is needed, simplifying maintenance.
Can the CD50 CDM-2 be used in server rooms?
Yes. CO2 leaves no residue and does not damage sensitive electronic equipment, making the CD50 CDM-2 well suited for server rooms, data centers, and laboratories. Ensure proper ventilation protocols are followed.
Does the CD50 CDM-2 have a pressure gauge?
CO2 extinguishers are typically weighed rather than gauged to verify charge. The CD50 CDM-2 should be weighed periodically to confirm proper agent level per NFPA 10 maintenance requirements.
