Product Series
Air Separation Unit & Plant Manufacturer
Our air separation units and on-site gas generation systems are engineered to replace costly bulk liquid gas supply with dependable on-site gas production. By separating ambient air into its main constituent components, these systems provide continuous, high-purity industrial gases directly to your production lines.
Core Equipment Series
PSA Nitrogen & Oxygen Generators
Adopting pressure swing adsorption (PSA) technology, these cost-efficient units are developed for large-capacity on-site gas production.
Membrane Gas Separation Systems
Featuring compact structure and low maintenance requirements, these units are well-suited for confined spaces and mobile/skid-mounted applications.
We deliver dedicated gas supply solutions for multiple industries including metallurgy, petrochemical, electronics, thermal processing, food packaging and automotive manufacturing. We supply durable, high-reliability equipment ranging from standalone units to full turnkey solutions, helping clients cut operating costs and guarantee uninterrupted production.

Air Separation Unit Industry knowledge
Zhejiang Baiao Gas Equipment Co., Ltd. manufactures five air separation product lines — PSA nitrogen (BAN), PSA oxygen (BAO), VPSA oxygen, membrane nitrogen (BAM), and carbon-supported nitrogen purification (BCN) — that share one thing in common: none of them are cryogenic. The sections below explain what that distinction means in practice, how the technologies compare on the parameters that matter for specification, and how customization actually works on an order.
Cryogenic vs. Non-Cryogenic: Why Most Enquiries Are About PSA/VPSA
Cryogenic air separation liquefies air below roughly -180°C and separates oxygen, nitrogen and argon by their different boiling points — capable of very high purity (oxygen above 99.5%) and multiple gas products at once, but requiring a multi-stage plant, a pre-cooling startup that can take hours, and specialized operating staff.
PSA and VPSA technologies adsorb a single target gas from compressed air at ambient temperature instead of liquefying it, trading multi-gas output and the very highest purity tier for a simpler process: startup in minutes rather than hours, fewer moving parts, and lower installation cost. For buyers who need one gas — nitrogen or oxygen — at a purity below the cryogenic ceiling, PSA/VPSA is generally the more practical starting point, which is why most enquiries addressed to air separation unit manufacturers are, in practice, about this equipment category rather than cryogenic plant construction.
Comparing Baiao's Non-Cryogenic Product Lines
| Series | Flow rate | Purity | Mechanism | Typically best suited to |
|---|---|---|---|---|
| PSA Nitrogen (BAN) | 5–3,000 Nm³/h | 95–99.999% | Carbon molecular sieve | High-purity nitrogen at higher delivery pressure (up to 0.8 MPa) |
| PSA Oxygen (BAO) | 1–1,000 Nm³/h | 80–95% (std. 93%) | Zeolite molecular sieve | Smaller-to-mid oxygen flow at usable outlet pressure (up to 0.5 MPa) without a booster |
| VPSA Oxygen | 100–5,000 Nm³/h | 70–94% (typ. 90–93%) | Zeolite molecular sieve, vacuum desorption | Larger continuous oxygen demand, where lower energy consumption per Nm³ matters more than outlet pressure (output is low-pressure and usually boosted) |
| Membrane Nitrogen (BAM) | — | Moderate (below PSA's purity ceiling) |
Hollow-fiber membrane | Confined spaces or skid-mounted/mobile installations, where mechanical simplicity outweighs purity |
Ranges above are Zhejiang Baiao Gas Equipment Co., Ltd.'s published parameters for each series; the exact figures for a given order depend on the specific model selected.
What "Custom Air Separation Unit" Means in Practice
Within each technology, capacity, purity, and delivery pressure are configured to the order rather than sold as one fixed unit. The BAN series alone, for example, is published across purity grades from 97% up to 99.999%, with flow rates from 5 Nm³/h to 3,000 Nm³/h and a different footprint at nearly every capacity step — so a custom air separation unit typically means selecting the combination of these parameters that matches a declared gas consumption and purity requirement, then confirming footprint and installation format (fixed, skid-mounted, or containerized) for the site. This is the normal way a custom air separation plant order is specified, not an exception to a standard catalog process.
Frequently Asked Questions
Does Zhejiang Baiao Gas Equipment Co., Ltd. manufacture custom air separation units, or only standard models?
Capacity, purity, and delivery pressure are configured per order across the BAN, BAO, VPSA, and BAM series — see the comparison table above for each series' published range. A custom air separation plant is the normal way these systems are supplied, rather than an exception made to a fixed catalog model.
Does Zhejiang Baiao Gas Equipment Co., Ltd. export air separation plants outside China?
Yes. As an air separation equipment exporter, the company supplies both standalone units and full turnkey systems to industrial customers outside China, alongside its domestic sales network covering more than 30 provinces.
Can equipment be supplied as a standalone unit, or only as part of a full system?
Both. Buyers who only need one component can order a standalone PSA or VPSA unit, while projects that specify compression, gas purification equipment, and separation together can be quoted as one turnkey system — this is a common request among air separation unit suppliers' industrial customers integrating equipment into an existing plant.
What certifications does Zhejiang Baiao Gas Equipment Co., Ltd. hold?
A High-Tech Enterprise Certificate, along with Quality Management System, Occupational Health and Safety Management System, and Environmental Management System certifications — all listed on the site's Certificates page.
As a China-based air separation unit manufacturer and factory, Zhejiang Baiao Gas Equipment Co., Ltd. designs and produces the PSA, VPSA, and membrane technologies compared above in-house, rather than trading equipment sourced from third parties.
