Optional equipment for reciprocating compressors
Oil for reciprocating compressors
Please use Anest Iwata's genuine oil for long lifetime of compressors. There are three sizes, 0.5, 1.0 and 1.5 liters.

Anti-dust filter kit

(fitted to 5.5kW and above as standard accessory)

A good installation site is ideal to operate compressors without any trouble for a long time. But when you are forced to operate compressors at a dusty site, you are recommended to use our anti-dust kit which prevents dust from entering through open section of crankcase, resulting in protection of inside parts such as bearings.

Air transformers
An air transformer is a combined set of air filter and air regulator; an economical and compact air filter.
RR-AP4B : The right outlet (viewed from the front) supplies non-regulated air from air receiver, and the left outlet supplies regulated air pressure controlled by pressure gauge.
FR : Compact type. It can be easily fitted anywhere.
RR-A : The right outlet (viewed from the front) supplies non-regulated air from air receiver, and the left outlet supplies regulated air pressure controlled by pressure gauge.
RR-AS : Both outlets supply regulated air pressure and increase efficiency.
RR-AT : For high pressure use (0.98Mpa {10kgf/cm2}and above).
