2％percent difference, probably due to service
5'％ percent difference. I think it's workmanship
10% difference. Must be materials
The price difference of 20% is not an order of magnitude
The age of transparency and thin margins
Please give your time to someone who knows what you're doing and is reliable.
Piston Flow Type FM200 Gas Suppression System
The use of FM200 fire extinguishing agent as a fire suppressant is not prohibited by the montreal protocol. It is a clean agent that belongs to a class of compounds that was introduced specifically to facilitate the phase-out of ozone depleting gases, such as Halon 1301. It is the most widely used of the chemical replacements for Halon 1301. It is an agent that has been used successfully to help protect tens of thousands of high technology facilities in 70 countries around the world.
FM200 gas piston flow type fire suppression systems can be ideal for use in occupied areas. Independent toxicity studies have established that the agent is low in both acute and chronic toxicity with high safety margins between its normal use concentrations and the no observable adverse effect level (NOAEL).

System Composition
This system mainly consists of agent storage cylinder, container valve, driving cylinder group, adding pressure cylinder group, distributing valve, liquid flow check valve, gas flow check valve, safety valve, pressure switch, frame, nozzle, high pressure hose, pressure-relief device, level gauge, relief valve, pipe system, which can constitute the unit independent system. Combined distribution system and other forms can implement fire protection for single and multiple zones.
Pipe fittings are those conduits to connect extinguishing device and guide agent into protective zone, like high pressure galvanized steel pipe and flange and elbow.
Electrical accessories are those things which are used to detect and monitor whole protective area and control whole system, also warn people to evacuate and prevent from fire expansion.
These integrated three parts will be efficient to detect and supervise and alarm and extinguish fire automatically.
