VARIANTS DT 4.4

Within the DT 4.4 series, a distinction is made between 2 variants.
The DT 4.4 DC is a special version with DC drive.
DT 4.2-4.8 (standard)
The pump is a classic dry-running rotary vane compressor.
It consists of a housing, the eccentrically installed rotor (2), the radially
moving vanes (3) and the inlet and outlet (4+6).
When the rotor turns, gas flows through the intake filter (5) into the
enlarging chamber (1) until it is shut off by the next slide valve. The
enclosed gas is then compressed and conveyed through the outlet (6)
into the connected pressure line.
