Air Purifier
　　 YJ mobile self-purifier is an air purification equipment which provides local air purification environment. It is composed by pre-filter, fan, high efficiency air filters and cabinet. The outside cabinet is made of cold-rolled steel, the surface paint handling , simple structure, easy to use, it also can be carried out after installation of indoor air circulation for 10000-100000 class of the environment and when the working place constantly changes.

GKF series efficient delivery outlet is made of high quality cold-rolled thin steel plate, the surface electrostatic spray. It has the advantages of simple structure, reasonable air distribution, can be used as the terminal unit is directly arranged on the new high Or alteration of the levels of clean room ceiling. Technical parameters： 1.Filtration efficiency：≥99.995％ 2.Initial resistance：≤235.44％(24mmH2O)

Technical parameters: air inlet side interface and top interface two forms

Control Valve

      FSD(F)-70 Fire control dampers        PFSD (W) 24/0.7-280 smoke damper        FSD-（J）24/0.7-70 Smoke fire damper

FSD(F)-70 Fire control dampers:
Application
Fire control valve is used in air conditioning system which has the fire safety requirements. In case of fire , the temperature of the blown fuse fusible ring 70 degrees . The valve is closed , the exhaust system for the fire damper gets fuse when the temperature is 280 degree. The valve is closed when the fuse for the exhaust system of dampers at 280 degrees, cutting off the fire and smoke spread along the duct channel , the valve blade can be adjustable in 0-90 degree.
Function
（1）Manually changes the opening angle of the blades.
（2） The Fuse acts when the temperature is 70 degree and the valve is closed.
（3）Manually open or reset.
（4）According to the system requirements , increasing the number of devices and the operation of telecommunications systems or other interlock Fire systems.

PFSD (W) 24/0.7-280 smoke damper
Application
The pipe used in the exhaust system or exhaust fan suction port when the fire occurs in the supply DC24V operating device or manually open the valve action and discharge smoke. The temperature fuse acts when the exhaust gas flow temperatures up to 280 degrees and the valve automatically closes and blocks airflow.
Function
（1）Manually open the valve and reset.
（2）Smoke element emits fire emergency, the control center supplies DC24V power output , so that the valve is open.
（3）The fuse acts when the temperature is 280 degrees , re- close the valve.
（4）The Valve acts when supply the output electrical signal ,and be connected with fire protection system interlock.
