8.2. Accessories

Accessories are available for compressor directly from the manufacturer (by special request in an order) or may be ordered directly from the manufacturer at a later time, see below. Individual accessories may be combined.

Accessories not included in the standard order must be ordered separately!

8.2.1. DK50 4x4VRT/M performance enhancement kit

If the performance of an existing DK50 4x4VRT compressor is insufficient, the manufacturer has developed an accessory DK50 6x4VRT/M performance enhancement kit. The DK50 4x4 VRT/M conversion kit converts the existing compressor into a fully functional DK50 6x4VRT/M compressor with the required parameters in an efficient manner at optimal cost.

9. EQUIPMENT FUNCTION

The compressor produces oil-free, dry, filtered compressed air to power pneumatic devices and equipment used in dental clinics and laboratories, hospital departments and more.

Compressor air pumps (11) draw in atmospheric air through the inlet filters and compress it through check valves and into the compressed air system. From there, the compressed air proceeds to the cooler (8), in which the compressed air is cooled for the first time and condensate is produced. The air

then passes through a water separator and into the condensing dryer (9). This continues to lower the temperature of the air and produces more condensate. The temperature then rises to reduce the relative humidity. The clean, dry air then passes through a check valve and enters the air tank (2). Condensate from the water separator and the dryer is drained off into a 10 l vessel in the condensate drain kit. The dryer ensures the continuous and no-loss drying of the compressed air. The treated compressed air is then ready for additional use in the air tank.
