PRODUCT DESCRIPTION
6. VARIANTS
The compressor is manufactured according to its intended application in the following variants:
DK50 2V MOBILE MINI
compressor in a cabinet with effective soundproofing
DK50 2V/M MOBILE MINI
compressor in cabinet with air dryer
DK50 2V MOBILE MINI
The compressed air from the compressor is not suitable for operating breathing
equipment or similar devices.
7. PRODUCT FUNCTION
7.1. Compressor without dryer
(Fig. 1) The air pump (1) draws in air through an inlet filter (7) and compresses it through a check
valve (3) into an air tank (2) from which the appliance draws compressed air. If the pressure in the
air tank drops to the switching pressure, the pressure switch (4) turns on the compressor and the
compressor supplies compressed air to the air tank until it reaches the switch off pressure, at which
time the compressor switches off. The pressure hose is vented through the relief solenoid valve
once the compressor unit is shut off. The safety valve (5) prevents the pressure in the air tank from
rising above the maximum permitted value. Condensate from the air tank (2) is automatically drained
at regular intervals trough the condensate separator with filter (11) into the condensate collection
vessel (12) via the condensate drain solenoid valve (10). Compressed, oil-free filtered air is stored
in the air tank ready for use.
7.2. Compressor with membrane dryer
(Fig. 2) The air pump (1) draws in air through an inlet filter (7) and compresses it, feeding it to the
cooler (16) through the filter and the non-return valve (3) into the dryer (15), and feeds the clean
and dry air into the air tank (2). A part of the air is released from the dryer with the captured moisture,
PRODUCT DESCRIPTION
06/2023 11 NP-DK50 2V MOBILE mini_MD-5_06-2023
which is manifested as a light air stream along the body of the dryer (15). Condensate from the filter
is automatically drained at regular intervals into the collecting bottle (12) via the condensate drain
solenoid valve (10). The dryer ensures continuous drying of the compressed air. The drain valve
drains condensate from the air tank when drying performance is checked. Compressed, oil-free
filtered air is stored in the air tank ready for use.
For the membrane dryer to work as intended, the dryer is connected directly to the air tank without
the use of a check valve. As the membrane dryer contains selective membrane fibres, there is a
small amount of air leakage through them (about 0.5 bar/30 min).
As a result, there is a gradual, slow drop in pressure even when there is no demand for compressed
air (from the air tank), however, this is not a malfunction.
The pressure tank is dry and does not need to be drained.
7.3. Compressor cabinet
(Fig. 3) The cabinet features rolling casters (2 with locks, 2 without locks) so that the internal shape
of the cabinet defines the position of the compressor itself. The rolling casters and the rigid structure
of the cabinet itself ensure easy and simple manipulation of the cabinet. Remove the 2 quick
closures to open the cabinet (19).
The following are located on the top panel on the front side of the cabinet: outlet pressure gauge
(2), pressure regulator (1), power switch (5) and hour counter (3). The connector (24) is located in
the lower portion of the cabinet's rear panel. The compressed air outlet (15) with an internal G1/4"
thread is located on the upper portion of the cabinet. A hose bushing (24) is installed in order to
serve as a condensate drain. The compressor runs in automatic mode when the power switch (5)
on the cabinet is switched on.
The following are located on the rear of the cabinet: cooling fans (15) to exhaust hot air from the
cabinet through the hot air exhaust ventilation openings in the cabinet. The cooling fans switch on
when the temperature switch reaches 40 °C and run until the temperature inside the cabinet drops
below 32°C.
Risk of compressor overheating.
Make sure that there are no obstacles at the cooling air inlet into the cabinet
(around the bottom part of the cabinet) and at the hot air outlet on the top back
side of the cabinet.
If the compressor is placed on a soft floor, e.g. carpet, create space between the
base and the floor or the cabinet and the floor, e.g. underlay the footings with
hard pads to ensure sufficient cooling of the compressor.

INSTALLATION
8. INSTALLATION CONDITIONS
Compressors may only be installed and operating in dry, well-ventilated and clean
environments with environmental parameters that meet the requirements specified in
Technical data. The compressor must be installed so that it is accessible at all times for
operating and maintenance. Please ensure that the label on the device is readily accessible.
The compressor must stand on a flat, sufficiently stable base (be aware of the weight of the
compressor, see Chapter Technical data).
Compressors may not be operated outdoors or in otherwise wet or damp environments. Do
not use the compressor in the presence of explosive gases, dust or flammable liquids.
Before connecting the compressor to medical equipment, the supplier must confirm that it
meets all requirements for its use. Refer to the technical data of the product for this purpose.
When a unit is to be built-in, classification and evaluation of compatibility must be done by
the manufacturer or supplier of the product to be used.
Any other use or use outside this framework is not considered as intended use. The
manufacturer is not responsible for any damages arising from such use. The operator/user
assumes all risks.
Risk of incorrect installation.
Only a qualified professional can install the compressor and place it into
operation for the first time. His obligation is to train the operating personnel on
the use and maintenance of the device. He shall confirm installation and training
of operators by an entry into the installation record.
Remove fixing elements of the pumps once the compressor has been assembled
and balanced at the final installation place.
Risk of burn or fire.
During compressor operation, the pump parts may heat to temperatures
dangerous for contact with persons or materials.
Risk of damage to the device.
The appliance must be located minimally 100 mm from the wall for enabling
blowing of cooling air. Non-observance of the given distance may be the cause
of damage to the compressor and case!
9. COMPRESSOR ASSEBLY
9.1. Manipulation and fixation removal
Unpack the compressor from the packaging.
Remove the front panel Z after releasing the quick closures (R) and disconnect the
grounding wire (U).
Remove the fixation components of air pump - X and Y
Prior to installation, ensure that the compressor is free of all transport packaging
and stabilizers to avoid any risk of damage to the product.
Remove fixing elements of the pumps once the compressor has been assembled
and balanced at the final installation place.
INSTALLATION
NP-DK50 2V MOBILE mini_MD-5_06-2023 20 06/2023
Fig. 4: Releasing the pump
Once the panel is installed, the grounding wire from the cabinet panel must be connected
and the cabinet must then be closed and secured with screws.
Connect devices to the compressed air outlet on the cabinet.
Insert the mains plug into a rated outlet circuit.
If the bracket and tank are installed on the side of the cabinet, ensure that at least
150 mm of space is kept between the cabinet and any nearby furniture. A smaller
distance can result in problems when draining the tank is needed.
Hazard of damage to dryer.
The condensate vessel must be on the floor in order to ensure the dryer operates
properly. Otherwise the dryer may be damaged.
The vessel must be moved upwards when the compressor is moved.
