Start with what you are protecting. Clean agent extinguishers discharge a gas that evaporates and leaves no residue, so they suit live electrical equipment, servers, control panels and delicate instruments where dry powder would cause secondary damage and long cleanup.
Then pick the agent. HFC-236fa (RQ series) and FE-36 (HQ series) are established halocarbon agents, with the FE-36 units using Chemours UL listed gas with zero ozone depletion potential. FK-5-1-12 fluoroketone is the newer option, listed with low ODP and low global warming potential, and it carries a 5A:21B rating under EN in addition to the 1A:21B Indian rating.
Match the size to the risk and the walking distance to the nearest unit. All three lines come in 2 kg, 4 kg and 6 kg. A 2 kg unit typically covers a single panel or desk area, while larger sizes suit bigger rooms.
Choose the body finish last. Mild steel with polyester powder coating is the usual choice; stainless steel bodies are used in front-of-house areas, hospitals, hotels and clean rooms where appearance and finish matter. Call or WhatsApp +91 92440 89060 for prices and a site-wise list.
