Description
The ZEPHYR DLR are two shaft, rotary lobe compressors, where two claws are rotating contact-less and dry in opposite
directions in a housing and are synchronised by a pair of gears. The pumping chamber is oil free. The synchronised drive
gears and the A-side bearings for the rotors are oil lubricated. The drive gears and the A-side bearings are fitted into
a gear chamber which also contain the oil tank. The oil tank is designed so that at all rotational speeds, bearings and
gears are supplied with the correct amount of oil. ZEPHYR 400 and 500 have on the B-Side also greased bearings.
The pumping chamber is separated from the gear chamber using labyrinth seals. The sealing system can be enhanced
with sealing gas (special version).
The ZEPHYR is enclosed in a sound box. The cooling takes place over the coupling fan. The fresh cool air (E) is sucked
in and the warm air is exhausted through the vents (F).
All the compressors are driven by a direct flanged three phase, standard TEFV motor via a pin and bush coupling.
Pressure can be adjusted to the required levels, however, they are limited to a maximum point (see regulating valve (D)).
Optional extras: As required, non-return valve (ZRK), suction filter (ZAF), motor starter (ZMS), inlet silencer (ZSZ) (see
picture ), soft starter (ZAD) and silencing hood.
