Industry Challenges

Understanding the specific thermal and environmental demands of Air Cushion Blower and Air Mat Systems environments is the foundation of every Herays solution.

Air cushion and air mat systems — including inflatable industrial work mats, pneumatic lifting cushions, air flotation tables for glass handling, air bearings for precision equipment positioning, and pressurized anti-decubitus mattress systems for medical use — require blower systems that maintain consistent low-pressure airflow to a distributed air distribution structure. The application demands are different from standard packaging air cushions: these systems operate continuously, often have critical safety or positioning accuracy implications, and may be used in environments where noise, vibration, and power consumption are all constrained.

  • Sustained low-pressure delivery — air mat systems typically require 0.1–2 kPa over-pressure across a large surface area. The blower must maintain this pressure across the full range of surface perforation or distribution port configurations.
  • Quiet operation for medical and office environments — anti-decubitus mattress blowers must be quiet enough for use in hospital ward environments (target below 35 dBA at 1 m); air flotation positioning tables in cleanroom or laboratory settings have similar acoustic constraints.
  • Vibration-free or low-vibration operation — air bearings for precision equipment positioning require the blower to operate without transmitting mechanical vibration through the air supply line into the supported equipment. Vibration isolation at the blower mount and smooth motor commutation are both required.
  • Medical-grade materials for patient-contact applications — anti-decubitus and therapeutic air mat systems require blower housing and outlet duct materials that are biocompatible and resistant to disinfection chemicals (bleach, isopropanol, quaternary ammonium compounds).
  • 12V or 24V DC for portable and battery-powered applications — portable air cushion systems for field use, camping, and emergency applications run from battery supplies at 12V or 24V.

Herays centrifugal BLDC blowers for air mat and air cushion systems are available in 12V and 24V variants with low-noise operation and continuous duty ratings suitable for sustained air distribution applications.

Specifications relevant to air cushion and air mat blower selection:

  • Topology: Centrifugal BLDC blower
  • Voltage: 12V or 24V DC
  • Pressure range: 0.1–5 kPa (matched to application requirement)
  • Noise target: below 35–45 dBA at 1 m depending on application
  • Materials: standard PBT housing; chemically resistant options available for disinfection-compatible applications
  • Mounting: anti-vibration mount options available

How do I size a blower for an air flotation table? Sum the total perforation area across the table surface, estimate the airflow through each perforation at your target operating pressure (using Q = Cd × A × √(2ΔP/ρ) where Cd is the discharge coefficient for your perforation geometry), then total the required flow. Add 20% margin for supply line losses and fit the blower to operate at 70–80% of maximum speed at this flow and pressure — this leaves headroom for table loading variations.

What causes air pressure fluctuation in an anti-decubitus mattress blower system? The most common causes are: (1) partially blocked air distribution tubes or nozzles from fabric compression or debris; (2) blower speed hunting from an unstable control loop; (3) air leaks at mattress seams or connector joints. Regular cleaning of the mattress distribution system and a periodic blower speed check (via tachometer output) identifies the root cause of pressure instability.

How is a medical anti-decubitus blower different from a packaging air cushion blower? Medical applications require biocompatible materials, resistance to hospital disinfectants, very low noise (35 dBA max), and often IEC 60601 electrical safety compliance. Packaging blowers are specified primarily for throughput and cost. The blower motor topology and performance curve may be similar, but the housing materials, motor insulation class, safety documentation, and noise target differ significantly.
