PSA Package Equipment: Dryer, Filtration and Air Receiver
The feed-air package that goes with our PSA generators: air dryer, filtration stages and air receiver, sized together so the air reaching the sieve bed is clean, dry and oil-free.
We size a complete PSA package with dryer, filtration and buffer tank rather than supplying the generator on its own, so the compressed air reaching the sieve bed is clean and dry enough for the process.
The published feed-air requirement for our PSA systems is compressed air at 0.6–0.8 MPa with a dew point of -40°C or lower and oil-free.
The air dryer brings the moisture load down, the filtration stages remove oil aerosol and dust carried over from the compressor and receiver, and the air receiver buffers the feed-air supply between the compressor and the PSA towers.
The generator inside the package delivers 90–95% O₂ at 1–500 Nm³/h, with outlet pressure from 0.1 to 0.4 MPa and energy use of 0.3 to 0.5 kWh per Nm³, using zeolite molecular sieve in a twin-tower PSA cycle.

| Flow | 1–500 Nm³/h |
| Outlet pressure | 0.1–0.4 MPa (adjustable) |
| Feed-air dew point | -40°C or lower |
| Energy use | 0.3–0.5 kWh / Nm³ O₂ |
| Adsorbent | Zeolite molecular sieve (ZMS) |
| Technology | ZMS twin-tower PSA (zeolite molecular sieve), continuous on-site supply |
| Feed air | 0.6–0.8 MPa, dew point ≤-40°C, oil-free |
| Startup time | ≤30 minutes to rated purity |
| Control | PLC automatic; optional HMI touch screen |
| Typical duty | Air dryer, filtration stages and air receiver supplied as one package with the PSA generator |
The PSA oxygen range is published as a purity and capacity configuration rather than a numbered model table: fix the required oxygen flow first, then confirm purity, outlet pressure and energy use for the duty.
- Adsorption towers: two adsorber vessels alternate between adsorption and regeneration, so the oxygen supply is continuous.
- Molecular sieve: zeolite molecular sieve (ZMS) selectively adsorbs nitrogen from the compressed air so oxygen passes through as product gas at 90–95% purity.
- Air dryer: the package includes an air dryer that brings the compressed-air moisture load down so the feed-air dew point requirement is met before the air reaches the sieve bed.
- Filtration: filtration stages remove oil aerosol and dust carried over from the compressor and receiver, protecting the sieve bed.
- Air receiver: a buffer tank (air receiver) between the compressor and the PSA towers steadies the feed-air supply.
- Control cabinet: PLC automatic control with an optional HMI touch screen; the control cabinet manages the valve cycle and the operating parameters.
- Purity monitoring: an oxygen analyser monitors the purity of the product oxygen, and its calibration is checked on schedule.
- Feed air: compressed air at 0.6–0.8 MPa with a dew point of -40°C or lower, oil-free.
- Air dryer: lowers the moisture content of the compressed air so the feed-air dew point requirement is met before the air reaches the sieve bed.
- Filtration: removes oil aerosol and dust carried over from the compressor and receiver, protecting the sieve bed.
- Air receiver: buffers the compressed-air supply between the compressor and the PSA towers.
- Sized as one system: generator, dryer, filtration and receiver are selected together from the required oxygen flow and purity.
- Control cabinet: PLC automatic control with an optional HMI touch screen, managing the valve cycle and operating parameters.
- Purity monitoring: an oxygen analyser monitors product purity and its calibration is checked on schedule.
- State the required oxygen flow and purity, since these set the generator size and the package around it.
- Check the available compressed-air supply against 0.6–0.8 MPa, a dew point of -40°C or lower and oil-free.
- Confirm the outlet pressure against the 0.1 to 0.4 MPa range.
- Note the energy use of 0.3 to 0.5 kWh per Nm³ when sizing the power supply and operating cost.
- Allow installation space for the dryer, filtration stages and air receiver alongside the generator skid.
- State the operating hours, ambient conditions and available utilities so the whole package can be quoted.
What is included in a complete PSA package?
A complete package covers the PSA generator together with the air dryer, filtration stages and the air receiver (buffer tank).
What feed-air quality do the PSA systems need?
The published requirement is compressed air at 0.6–0.8 MPa with a dew point of -40°C or lower and oil-free.
Can the package be quoted as one system?
Yes. Send the required oxygen flow, purity, outlet pressure, application and operating hours and we size and propose a complete PSA package.
Why condition the feed air at all?
Oil aerosol, dust and moisture carried over from the compressor and receiver reduce the performance and the life of the sieve bed, so the dryer, filtration and receiver protect the generator.
Which gas generator sits in the package?
The published package uses a ZMS twin-tower PSA generator delivering 90–95% O₂ at 1–500 Nm³/h, 0.1–0.4 MPa outlet and 0.3–0.5 kWh per Nm³.

How to Choose a Complete PSA Package
Quick answer: A complete PSA package includes the generator, air dryer, filtration stages and air receiver. Start from the required oxygen flow and purity, then check the feed-air supply against 0.6–0.8 MPa, dew point ≤-40°C and oil-free.
What should a PSA package include?
The generator itself plus the feed-air conditioning that protects it: an air dryer, filtration stages and an air receiver (buffer tank), sized together from the required oxygen flow and purity.
How do I check my compressed-air supply?
Measure the available pressure and capacity against the published requirement of 0.6–0.8 MPa, dew point -40°C or lower and oil-free. The PSA generation guide explains why air quality governs sieve life.
What else should I send with the enquiry?
Required flow and purity, outlet pressure, application, operating hours, ambient conditions, installation space and the available utilities, so the whole package can be quoted as one system.
