Cooler
The compressor contains of an oil-free piston (16) driven by a low-maintenance single-
phase electric motor. Compressed air is cooled in the cooler (23) where condensed water
is separated into a separate tank (14). Incoming air passes through two filters (15, 21)
undergoing double filtration as it passes through the system (19). The model with a
membrane dryer is intended for applications that require a higher level of air dryness.
Constant outlet pressure is maintained by pressure regulator (20). The built-in air tank (18)
enables peak air consumption of 200 L/min.
The device may be used as a standby compressed air source. In this configuration, the
respiratory equipment is supplied with compressed air from the central compressed air
lines of the medical facility. Air pressure in the central compressed air line is monitored by
a pressure sensor. If the pressure is sufficient, the compressor stays in STANDBY mode.
If the pressure falls, the control unit automatically puts the compressor into operation.
When the compressor is used as the main source of air, the control unit determines its
operation according to the current demand for air. If air consumption is zero, the device
switches to STANDBY mode.
The compressor is equipped with indicators for outlet pressure (1), operating hours (6),
power status (8), drying status (4) and battery condition (7). Acoustic and optical alarms
activate to warn of high operating temperature (3), low outlet pressure (2) and loss of
power (5).
