Hydrogen compressor, negative intake pressure, oil-free
Thread Content
I’ve just arrived; I hope my fellow experts can offer me a lot of guidance! New Year’s Day is coming up soon. Wishing everyone a happy New Year! I have a question for everyone. I am looking for a hydrogen compressor with the following specifications: at the inlet side, it should be capable of operating from positive pressure to negative pressure. The desired pressure range is as follows: in terms of gauge pressure, the reading on the pressure vacuum gauge should be between 2 atm and -0.5 atm [0.2 MPa to -0.05 MPa]; in terms of absolute pressure, it should be between 3 atm and 0.5 atm [0.3 MPa to 0.05 MPa]. It is hoped that the lower limit of negative pressure can be as low as possible. If this pressure range is difficult to meet, the lower limit for negative pressure can also be relaxed. For example, for gauge pressure, the reading on a pressure vacuum gauge is 2 atm to -0.2 atm [0.2 MPa to -0.02 MPa], while for absolute pressure in physics, it is 3 atm to 0.8 atm [0.3 MPa to 0.08 MPa]. For example, in the case of gauge pressure, the reading on a pressure vacuum gauge is 2 atm to -0.1 atm [0.2 MPa to -0.01 MPa], while for absolute pressure in physics, it is 3 atm to 0.9 atm [0.3 MPa to 0.09 MPa]. Another example is the case of slight negative pressure. For gauge pressure, the reading on a pressure vacuum gauge is 2 atm to -0.05 atm [0.2 MPa to -0.005 MPa (-5000 Pa)], while for absolute pressure in physics, it is 3 atm to 0.95 atm [0.3 MPa to 0.095 MPa]. The desired pressure range for the exhaust side is as follows: in terms of gauge pressure, the reading on a pressure vacuum gauge should be between 5 atm and 10 atm [0.5 MPa to 1 MPa]; whereas in terms of absolute pressure in physics, it should be between 6 atm and 11 atm [0.6 MPa to 1.1 MPa]. The pressure range given above is only the desired optimal range; it is also acceptable to slightly exceed this range. The hydrogen gas emitted contains no oil mist, grease fumes, or oil vapor. Please actively recommend compressor models and manufacturers that meet the above requirements; those selected will receive substantial rewards. First of all, thank you all for your attention!
Did my buddy study physics in college? It’s not hard to buy a reciprocating hydrogen compressor based on your parameters

We offer a completely oil-free system that enables near-isothermal compression, making it suitable for hydrogen transport… Please contact me – what process are you using? What is the traffic volume?
lk70: Thank you for your attention and for the information provided. I need to check the relevant materials. symc: Thank you for your attention and for providing the information. I’ll first get to know your company and learn about your products, and then get in touch with you.
I misread it; the exhaust pressure is actually 10 atm, I thought it was 1 atm :L
It’s difficult to choose a model without knowing the air volume, but considering the inlet and outlet pressures, our liquid ring compressor can also meet the requirements. Guaranteed oil-free.

Thank you for your interest. Could you please leave your contact information?
Thank you for your interest. Please leave your contact information so we can communicate further, okay? I’m an amateur when it comes to equipment such as pumps and compressors.
May I ask if the exhaust pressure of the products manufactured by your company is only 1 atm? Can it not be increased any further?
Could a two-stage configuration be used: in the first stage, the pressure of the gas is changed from negative pressure to normal pressure?； Later stage: Is it feasible to increase the gas pressure from atmospheric pressure to high pressure [for example, 5–10 atm]? Please let me know.
