Pure airflow and controlled processes for pharmaceutical production environments

Side channel blowers are indispensable components in a variety of industries that require reliable air conveying or vacuum generation. Thanks to their robust construction, energy-efficient motors, and maintenance-free operation, they offer a durable and cost-effective solution for demanding applications. (Copyright: SKVTechnik)

The pharmaceutical industry places particularly high demands on process air systems: maximum purity, absolute operational safety, and precise controllability. Vortex blowers are the first choice for applications requiring constant pressure or suction performance in hygienically sensitive areas. They operate without oil, lubrication, or maintenance-intensive components and deliver uniform airflow for packaging, extraction, ventilation, or drying — even under cleanroom conditions.

Application Examples

Air Supply for Cleanrooms

To ensure stable pressure conditions in airlocks and work areas of ISO-certified cleanrooms, vortex blowers are used. Their pulsation-free air transport enables uniform room pressure regulation — without particle generation from moving parts.

Extraction during Powder Filling

Controlled extraction is essential when handling pharmaceutical active ingredients in powder form to prevent contamination and cross-reactions. Vortex blowers with optional ATEX certification reliably extract airborne particles — both from filling stations and in isolator systems.

Blister and Packaging Machines

In packaging into blisters, pouches, or vials, vortex blowers are used to extract air, fix packaging materials, or support sealing processes through controlled compressed air supply. Their consistent airflow increases process safety and cycle accuracy.

Filter Drying and Active Ingredient Production

In production lines for tablets, capsules, or infusion solutions, vortex blowers provide ventilation for drying stations and filter systems. Due to their compact design, they can be integrated directly into isolated machine environments.

– Technical advantages for pharmaceutical applications
– Contactless operation: No particle emission — ideal for GMP environments
– Oil-free and hygienic: No contamination, maintenance-free operation
– Low vibration and quiet: No influence on sensitive measurement or filling systems
– Compact design: Easy to integrate into machine housings
– ATEX certification available: Suitable for use in explosion hazard areas with organic dusts or solvent vapors
– Compatible with frequency converters: Precise regulation according to process requirements
– Material options: Stainless steel connections, special anodizing, impregnation against chemical media

Typical System Configurations

For pharmaceutical applications, single- or two-stage vortex blowers (MS or MD) with moderate volume flows and stable pressure performance are typically used. Models such as R30MD or K05MD offer flow rates of 80–200 m³/h at pressures up to 400 mbar and are also available in ATEX versions. Integration into systems is either direct (e.g., vertically within the machine frame) or external with flexible soundproofing.

Safety and Qualification Requirements

Vortex blowers meet key requirements for pharmaceutical quality assurance:

– GMP-compliant design
– Validatable airflow
– Particulate-free operation
– Certifiable electrical safety (e.g., IE3 + ATEX)
– Easy to use in controlled zones (e.g., ISO 8 to ISO 5), especially with additional HEPA or ULPA filters on the inlet and outlet sides.

Practical Examples

– Active ingredient filling: Dust-free extraction during filling processes in cleanroom containers
– Blister packaging: Air extraction before sealing for solid dosage forms
– Sterile ventilation: Pressure regulation in airlocks and isolators
– Cleaning systems: Extraction of CIP or WIP media during drying phases

Advantages for Designers and Operators

– Easy integration into modular machine concepts
– No downtime due to wear parts
– Suitable for continuous processes without supervision
– Lower energy consumption through IE3/IE4 motors
– Maximum safety with minimal space requirements
