No, but it seems is not necessary. Its very dense. I made it from wood as a test to understand better how it works, before making some stuff in aluminum. It seems though it will perfectly work if wooden. it made from a solid kitchen cutting board. however sealing it is recommendable, due to humidity so it would not twist when dry or humid
it will suck probably more air from the actual part, which is has 3mm bottom /pine/

very useful thread thanks.
a few questions
i know nothing about compressors, can you provide any details incuding photos of how to connect up for sucking/to create vacuum?
a compressor turns on for 5 mins till its full then stops, how do you keep it ogint for an hour without stopping? release air whilst is drawing air in?

Hi andy
A compressor is controlled by a pressure switch,Tank empty switch it on and compressor will run filling the tank, when it's upto the set pressure the pressure switch kills the supply to the motor, as you use air the tank pressure drops below the switches set point,the contacts close and power is supplied to the motor increasing the pressure.
If using as a vac pump all you need to do is open the outlet valve on your tank so the switch will never see the cutout pressure.
There is usually a filter of some sort on the inlet, use this connection for pulling a vacuum.
Regards
Mike

Time for update.
Bought from ebay an Alcatel 2010 vacuum pump from Lithuania. WOW what a sucker! 7cfpm , 2 stage, 350W. So these days i have been finishing my new Vacuum Pump Station.
Basically the pump is mounted on old air compressor tank, driven by VFD as its motor is 3 phase 350w. The pump is fitted an original exhaust and DIY inlet filter and separator. The pump sucks -filter-hose-tank-quick connector. There is an vacuum sensor switch fitted to see pressure and eventually when i figure how to connect it to my VFD. May be i need a relay or sth. This is the part that i always don't understand...
will post a video later, just uploading it nowLast edited by Boyan Silyavski; 29-07-2016 at 01:43 PM.
