What compressed air does a medical device manufacturer need?
Medical device manufacturing runs on air that touches device components or enters a controlled environment, so the specification is oil-free to ISO 8573-1 Class 0, dried to a stable dew point, and filtered to match the ISO 14644 cleanroom class it serves. That air molds device components, drives assembly and fixturing, runs leak and flow testing, and supports packaging in controlled environments. The Class 0 supply comes from oil-free compressors so contamination is removed at the source, and the drying and filtration are matched to the point of use. The ISO 13485 quality system and any validation stay with the manufacturer; Brabazon supplies equipment and records that make the air quality straightforward to document.

Medical device cleanroom air specification guide
Air that touches a device component or enters a cleanroom is specified oil-free to ISO 8573-1 Class 0, with drying and filtration matched to the ISO 14644 room and point of use. The specification splits by where the air goes.
Air quality split by point of use
Cleanroom and contact air: Oil-free ISO 8573-1 Class 0 from oil-free compressors, dried and filtered to match the ISO 14644 room, with a sterile-grade final filter at the point of use.
Molding and test air: Class 0 supply with a stable dew point so molded surfaces stay clean and leak and flow test readings are repeatable, buffered by a correctly sized receiver.
Documentation: Equipment specifications and maintenance records that support your ISO 13485 air quality documentation. Brabazon supplies and services the equipment; the manufacturer owns the validation.
Run the numbers yourself
- Use the CFM calculator to size the oil-free compressor to combined molding, assembly, and test demand.
- Use the air receiver tank calculator to buffer leak-test and molding surges so test-line pressure stays stable.
- Use the compressed air leak calculator to price leaks that waste expensive Class 0 air and pull down cleanroom line pressure.
See our pharmaceutical and medical page and the electronics page for related Class 0 and cleanroom air guidance.

Where medical device plants use compressed air and vacuum
-
Device component molding
Oil-free air for mold actuation, part ejection, and blow-off on injection molding of device components where surface cleanliness is critical.
-
Cleanroom supply air
Class 0 oil-free air feeding tools, actuators, and equipment inside ISO 14644 controlled environments without adding hydrocarbon contamination.
-
Assembly and fixturing
Clean, dry air drives pneumatic assembly stations, presses, and fixtures that join and align small device components repeatably.
-
Leak and flow testing
Stable, dry test air at controlled pressure so leak and flow test results are repeatable and pass or fail decisions are trustworthy.
-
Packaging in controlled environments
Clean air for form-fill-seal and tray-seal packaging of sterile devices where product-contact air must not add contamination.
-
Part handling vacuum
Cleanroom-compatible vacuum for pick-and-place, fixturing, and degassing of small precision device parts.
-
Blow-off and static control
Dry, oil-free ionized blow-off clears particulate from parts and packaging ahead of inspection and sealing.
-
Air quality documentation
Equipment specifications and maintenance records that support the air quality documentation your ISO 13485 quality system requires.
What keeps medical device air clean and documented
Four disciplines keep a medical device air system out of the contamination and validation risk column.
-
Class 0 oil-free at the source
Air that contacts device components or enters a cleanroom is specified oil-free to ISO 8573-1 Class 0, meaning no measurable oil from the compressor. Oil-free compressors remove the contamination risk at the source rather than relying only on downstream filtration to catch oil carryover. That makes the air easier to validate and keeps a single filter failure from putting oil onto a device.
-
Drying matched to the cleanroom
Dew point matters in two ways: condensation ruins cleanliness and moisture skews test air. General cleanroom air is often dried to a 38 F pressure dew point, while critical lines and any run through cool space use desiccant drying to a negative 40 F dew point. The drying and filtration are matched to the ISO 14644 class of the room and the point of use so the air never carries moisture or particulate into a controlled area.
-
Repeatable test air for leak and flow testing
Leak and flow testing decides whether an assembled device ships. Test air has to hold a stable pressure and a consistent dew point, because pressure swings and moisture change the reading. A correctly sized receiver buffers the demand and a dryer holds the dew point steady, so the test measures the device and not the utility system behind it.
-
Documentation the quality system can use
An ISO 13485 quality system and its validation belong to the device manufacturer. What Brabazon provides is equipment configured to a defined air quality target plus the specifications and maintenance records that make documenting that air quality straightforward. We do not certify the manufacturer or perform the validation; we supply and service the equipment that supports it.
Recommended setup for medical device manufacturers
For a medical device plant, the package we configure most pairs oil-free rotary compressors supplying ISO 8573-1 Class 0 air with an air dryer holding a stable dew point and a filtration train that finishes with a sterile-grade filter at the point of use. General cleanroom air is dried to a 38 F dew point, while critical molding and test lines use desiccant drying to a negative 40 F dew point. An N+1 configuration is available where a compressor loss cannot be allowed to stop production. See the oil-free compressor page, the air dryers page, and the dryers and filters page for equipment details.
When to dry the whole plant to a negative 40 F dew point, and when not to:
drying every line to desiccant dew point is simple to document but costs energy on air that only
needs a 38 F dew point. Splitting the system so general cleanroom air runs refrigerated and only
the molding, test, and cold-run lines get desiccant drying saves energy without lowering the
quality where it matters. The split follows the point-of-use requirements, not a single blanket
dew point.
Typical project: Medical devices
Class 0 oil-free supply with matched drying keeps molded parts and test air clean
A common scenario in this industry is a device manufacturer expanding into the Minnesota medtech corridor that needs Class 0 air across molding, assembly, and leak test without contaminating parts or skewing test readings. A typical project starts when the existing supply relies on filtration downstream of an oil-lubricated compressor, so any filter fault risks putting oil on a molded component, and the test line pressure swings enough to affect leak-test pass and fail decisions. Brabazon-configured equipment solves this with oil-free compressors delivering ISO 8573-1 Class 0 at the source, a correctly sized receiver to hold test-line pressure steady, and drying split so general cleanroom air runs at a 38 F dew point while molding and test lines run desiccant-dried to a negative 40 F dew point. The manufacturer keeps the equipment specifications and maintenance records to support its own ISO 13485 air quality documentation.

Questions engineers actually ask us
What air quality do medical device cleanrooms need?
Air that contacts device components or enters a cleanroom is typically specified to ISO 8573-1 Class 0 for oil, which means no measurable oil from the compressor, along with a low dew point to prevent condensation and tight particulate filtration. Oil-free compressors provide the Class 0 supply at the source, and the drying and filtration are matched to the ISO 14644 cleanroom class the air serves.
Why is oil-free air used for medical device molding?
Injection molding of device components uses compressed air for mold actuation, part ejection, and blow-off, and any hydrocarbon carryover can contaminate the part surface and interfere with downstream bonding, coating, or sterilization. Oil-free compressors remove the contamination risk at the source rather than relying only on filtration to catch it, which simplifies validation of the molded component.
How does compressed air support medical device leak testing?
Leak and flow testing of assembled devices needs air at a stable, controlled pressure with a consistent dew point so that test results are not skewed by pressure swings or moisture. A properly sized receiver and a dryer holding a steady dew point keep the test air repeatable, which is what makes pass and fail decisions trustworthy on the assembly line.
