mobile compressed-air treatment

Mobile compressed-air treatment for professional outdoor use

Mobile compressed-air treatment systems are used when damp or hot compressor air must be treated directly at the worksite. Especially during sandblasting operations, condensate in the compressed air system can interfere with the transport of the abrasive media. Damp abrasive media can clump together, causing uneven dosing and work interruptions.

The current product line includes portable compressed-air aftercoolers, a high-performance coalescing filter, and dehumidification systems for higher flow rates. This allows users to configure a treatment system tailored to mobile compressors and various job site conditions.

Compressed-Air Aftercooler: Targeted Cooling of Hot Compressor Air

The portable compressed-air aftercoolers are designed for flow rates ranging from 3 to 25 m³/min at a maximum pressure of 12 bar. When the compressed air is cooled, some of the moisture it contains condenses and can then be separated. This reduces the amount of water that would otherwise accumulate in hose lines or at the point of use.

The product range includes both electric and pneumatic models. The electric version is a good choice if a suitable power supply is available at the site of operation. Pneumatically driven models offer an alternative when the system needs to operate as independently as possible from an additional power supply.

Coalescing filters for fine liquid droplets

The mobile high-performance coalescing filter constitutes an additional treatment stage. Coalescing filters cause fine liquid aerosols to coalesce into larger droplets, which can then be separated. In a mobile treatment chain, this stage can be particularly useful after effective cooling.

Dehumidification systems for 20 or 30 m³/min

Compressed air dehumidification systems with capacities of 20 or 30 m³/min are available for high mobile air volumes. Electric and pneumatic versions are also available here. This allows the system configuration to be adapted to the existing power supply and compressor power ratings.

Why Flow Reserve Is Important

A treatment system should be capable of reliably handling the actual air flow rate passing through it. If an aftercooler or filter is undersized, the pressure drop may increase and the available working pressure at the point of use may decrease. This is particularly relevant for sandblasting, because blast nozzles require high and continuous air flow rates.

The size of the blast nozzle, the desired operating pressure, and the compressor’s free air delivery should therefore be considered in conjunction with the mobile processing system. A high-performance compressor alone does not guarantee a stable blasting process if downstream components restrict the airflow.

Mobile processing is not a substitute for all stationary drying methods

Aftercooling, coalescence filtration, and mobile dehumidification effectively reduce moisture for many outdoor applications. However, if a specific, very low pressure dew point is required, appropriately designed drying technology is necessary. For industrial applications with particularly high dryness requirements, separate refrigeration and desiccant air dryers are available in the store.

Buy mobile compressed-air treatment

Anyone looking to purchase a mobile compressed-air treatment system should first determine the compressor power, maximum flow rate, operating pressure, and operating conditions. After that, they can decide whether a mobile aftercooler, a coalescing filter, a dehumidification system, or a combination of these is needed. For blasting applications, the goal is to ensure a compressed air supply that is as stable and dry as possible, reliably supporting abrasive transport and work performance.
