Compressed Air Quality Specification

This specification defines the Quality Unit–approved quality acceptance criteria and decision requirements for compressed air used in GMP-relevant operations.

Specification Type:
Authoritative Quality Control specification defining compressed air quality acceptance criteria and decision logic. This document does not define system design, maintenance, monitoring methods, or operational procedures.

1. Purpose

To establish Quality Unit–approved acceptance criteria for compressed air used in GMP operations, ensuring that compressed air does not introduce contamination or adversely impact product quality, material integrity, or equipment cleanliness.

2. Scope

This specification applies to compressed air systems where compressed air directly contacts products, components, packaging materials, or GMP-critical surfaces, or where such contact is reasonably foreseeable.

Applicable Business Domains include:

3. Ownership & Governance

Compressed air quality acceptance criteria defined in this specification shall not be modified outside approved QMS change control.

4. Compressed Air Quality Acceptance Criteria

Parameter Acceptance Criteria Applicability
Particulates No visible particulates; filtration suitable for GMP use All GMP-relevant compressed air use points
Oil / Hydrocarbons Free from oil and hydrocarbon contamination All GMP-relevant compressed air use points
Moisture Dry air with no visible condensate or water All GMP-relevant compressed air use points
Microbiological Contamination Compressed air shall not introduce microbiological contamination Where compressed air contacts exposed product or components

Where more stringent compressed air quality requirements are defined by product, process, or regulatory expectations, the more restrictive criteria shall apply.

5. Decision Logic

6. Escalation Requirements

Quality Assurance must escalate to Quality Control or QCO when any of the following occur:

7. Records & Evidence

Records supporting compliance with this specification include, but are not limited to:

This specification defines compressed air quality acceptance criteria and decision authority only. System design, filtration selection, maintenance, monitoring frequency, and testing methods are defined in separate controlled documents and shall not redefine the requirements herein.
