Tanabe TASK
Vijčani kompresor s ubrizgavanjem ulja u kućištu
Tanabe TASK is a packaged, oil-injected rotary screw compressor (male and female rotors) in a soundproof box, used on board for service and working air. Oil cools, lubricates and seals the screw end; an oil separator element cleans the delivered air and an integrated aluminium oil cooler / after-cooler is cooled by a fan. Capacity control is by automatic unload, unload stop and automatic start/stop from a pressure switch and unloader solenoid valve. The manual gives safety warnings, construction, oil and filter replacement, cooler cleaning, V-belts, lay-up, the periodical check chart and a troubleshooting table.

Oil and oil filter change
- Stop the compressor, isolate power and check oil pressure reads 0 MPa. str. 27Pressure inside can eject oil
- Fit the short drain pipe to the separator oil outlet valve and drain the oil. str. 27
- Unscrew the old filter cartridge with a wrench; grease the new packing thinly and fit by hand. str. 29
- Fill fresh oil to the H line and run; check for leaks. str. 27
Suction filter cleaning
- Remove the top board of the package, the butterfly nut and cover. str. 31
- Pull out the element and blow it with air under 0.7 MPa from inside and outside. str. 31
- Check for damage and refit with the wider flange downwards; replace every 2000 h. str. 31
Lay-up and restart
- Before lay-up renew the oil, run about 1 hour, drain the separator, close the outlet valve, cover motor, panel and filter; cut power. str. 33
- Before restart remove covers, check motor insulation is over 1 MΩ, drain the separator and start normally. str. 33
