Redstar Equipment presents a range of rotary screw, single-stage compression, oil cooled box type compressors designed for high performance, safety and durability.
The highly reliable DIS-1850SB box type compressors incorporate non-friction, twin screw airends, enabling the DIS series compressors to generate consistently steady streams of air. The special bearings incorporated into the airends are carefully selected for use with twin screws and are highly reliable and durable.
The DIS-1850SB box type compressors assure high efficiency and low fuel consumption with the engine speed control system developed by Denyo incorporating a highly efficient screw that saves fuel and improves performance at all rated conditions.
High overall operating efficiency is ensured from no-load to full-load conditions while fuel consumption has also been significantly improved at light and medium load levels.
The new type airend and large battery built into the compressors have improved start-up at low temperatures and a start relief valve also makes start-up easier.
DIS-1850SB box type compressors incorporate several features for a safe operation from start-up to shut-off.
All models for instance, are equipped with an automatic blowoff valve that releases residual air pressure when the compressor is shut off, making restarting easier. The DIS-130 and larger units are equipped with a protective device that prevents the machine from restarting accidentally due to residual air pressure.
All air compressors can be stopped merely by turning the engine key to the STOP position, eliminating the need for manual stopping levers or buttons used on previous models.
Unlike larger units equipped with automatic air bleeder or emergency shut-off devices as standard equipment, the DIS-90 and smaller units no longer require air bleeding. The engine can be started at any time without air bleeding.
DIS-600 and larger air compressors are coated with an anticorrosive substance that prevents damage due to salt and moisture. Stainless steel bolts have also been used on the exterior.
These small and lightweight compressors in the DIS series are equipped with a unique soundproofing system with the average value of noise at a distance of 7m in any direction being 64-76dB(A) at rated operation.
The lightweight and compact compressors feature a one-point lifting eye that makes moving the unit at the work site quick and easy. All 4-wheel trailer type units are equipped with parking brakes as standard equipment.
