A very suitable compressor for the VenoPulse is the Sil-Air 15D minicompressor which, in Norway, is provided by Amatec AS. This is a very silent (30 dB/A) unit that can easily be placed under a table.
For those who have chosen this solution there are a few practical hints when preparing the unit for use, described below:
Back view:
Side view:
Before starting the compressor the accompanying compressor oil (500 ml) must be inserted. Remove the rubber cap (5), place the plastic tube into the metal tube (6), and gently squeeze all of the oil content into the compressor. After filling, recap the metal tube.
Front view:
The on/off switch (7) is located at the top.
The compressor manometer (8) shows the tank reservoir pressure. The max. pressure is 6 bar.
The regulated (output) pressure is shown at the output manometer (9). This pressure is adjusted by the regulator wheel (10): Lift the wheel to unlock it, then turn it clockwise to increase output pressure - turn it counter-clockwise to reduce it. Adjust output pressure to appr. 3 bar.
To be able to connect the pressure hose from the VenoPulse a nipple (11, also shown below) has to be fitted to the regulator.
If condensed water or oil is accumulated in the container below the regulator it may be removed by gently turning the knob at the bottom.
The nipple has 1/4" threads and 1/4" tube for the hose. Fix the hose securely to the nipple.
IMPORTANT. Because of the constant bypass leaks of the VenoPulse pressure regulator the compressor will start every 5-10 minutes even when it is not used. To increase compressor lifetime it is advisable to either 1: turn of the switch (7), 2: Unplug the mains cord, or 3: Disconnect the pressure hose from the VenoPulse unit when the investigations are finished.
