Description

The C-DLR 401 and C-DLR 501 models has a connecting thread on the pressure side and an intake silencer
on the suction side. The incoming air is cleaned by a fi lter cartridge.
The C-DLR 401 and C-DLR 501 are double shaft rotary piston compressors in which the claws roll off
against each other contact free and dry. The counter-rotating claw rotors are synchronised by a gear pair in
the gearbox. The synchronous gearbox gear wheels and the bearing on the motor side are lubricated with
oil. These components are in a gearbox that also contains the oil supply. Oil conveying devices always en-
sure that the bearings and the gear wheels are suffi ciently supplied with oil at all permissible speeds.
The gearbox and the compression chamber are separated from each other by special seals. The gearbox is
sealed from the outside with shaft seals and O rings, the compressor chamber with piston rings. Between
them there is also another atmospherically ventilated area which can be loaded with sealing gas (special ver-
sion).
The C-DLR 401 and C-DLR 501 are encapsulated by an insulating hood. In order to dissipate compression
heat, the cooling air is sucked through between the machine and the hood using drum fan that sucks in the
fresh cooling air (Fig. 2/E) and discharges the heated air out of the cooling air outlet (Fig. 2/F).
The C-DLR 401 and C-DLR 501 are driven by standard fl anged three phase motors via a coupling.
To protect against overload a safety valve (Fig. 2/D) is fi tted as standard.

Areas of application

This contact free running claw compressors C-DLR are suitable for creating excess pressure between 0 and
the maximum limit (in bars) given on the data plate Fig. 2/N). Constant operation is permissible.
The compressor have fl ow rates of 400 m
side are given on the data plate (N). Data sheet D 888 shows the dependency of the fl ow rate on the excess
pressures.
If the unit is switched on more frequently (at regular intervals of about 10 times an hour) or at
higher ambient temperatures and intake temperatures, the excess temperature limit of the motor
winding and the bearings may be exceeded.Please contact the manufacturer should the unit be
used under such conditions.
If it is installed in the open air the unit must be protected from environmental infl uences, (e.g. by a
protective roof).
