Electrical power supply is not needed. It is the control panel which can perform operation and control of an operation interval only in supply of air.

※Please refer to the「Flow aid equipment combination」

Best for control in an explosion proof area

In a specific area with fear of dust explosion or an combustion accident, in case a knocker is used, N2 (nitrogen) can usually be used for substitution of air. It is the optimal controller for explosion accident prevention. Oxygen concentration is reduced to nitrogen and there is work which reduces establishment of dust explosion.

Clear in a protection level IP 44

It can be used with a indoor-outdoor use type also in the spot of an bad condition.

Air control type which does not need a electric power source is adopted

Operation interval control timer, and the manual operation / automatic change parts have adopted air control, and do not need a electric power source. (Operation interval is 180 seconds maximum)

Manual-Automatic combination type

Selection of manual operation/automatic operation can be performed using a selection switch.

Two or more set use is possible (HKA type)

RKV/RKD/RKVS30PA of the number of knocker use (Usually of piping) is 8 sets. 40/60PA is 6 sets. 4 sets of simultaneous control are possible for 80/100PA.(per set) (It is not concerned with a model at the time of relay piping, but it can be used to 10 per set)
