Whether you need temporary production expansion, replacement in case of failure or extra capacity during maintenance – we deliver quickly and ensure reliable operation, including optional remote monitoring.
Flexible renting, with no compromise on air quality.
Air treatment is the process by which compressed air is thoroughly cleaned and dried after compression. Compressors produce air containing vapor, oil aerosols, solid particles (such as dust, rust, dirt) and other contaminants. Without treatment, these elements can lead to corrosion in air lines, damage to pneumatic machinery, quality problems in finished products and increased maintenance.
An air handling system typically consists of a combination of:
air dryers (refrigeration, adsorption or membrane dryers) to remove moisture (water vapor);
Compressed-air filters and compressed-air line filters for removing solid particles, oil aerosols, oil vapors, and dust from the air;
oil-water separators and condensate drains to collect collected moisture and oil;
and sometimes additional activated carbon filters for gaseous contaminants and odor/vapor reduction.
The result: compressed air with the right air quality (according to relevant standards such as ISO 8573-1), with the right dew point, minimal contamination, ready for use in sensitive industries.
Selection of air treatment often involves consideration of which technology is the best fit for the application, capacity and requirements in air quality:
Refrigerated dryers
They cool the compressed air to condense water vapor. The condensate is then discharged. They provide typical dew points of approximately +3 °C or slightly higher, depending on type, load, and environment. They are relatively simple and energy-efficient.
Adsorption dryers
These achieve much lower dew points (often -40 °C or lower), and are suitable where very dry compressed air is needed (e.g. in paints & coatings, pharma, electronics). There are variants: heated, heat-less (without external heating), regeneration with compressed air or electric heating.
Membrane dryers
Membrane technology allows water vapor to escape through the membrane while keeping clean air. Few moving parts, relatively low maintenance, ideal for applications where moderate quality is required and space/energy is limited.
Pre-filters: for coarser solid particles, dust, airborne particles, and large oil aerosols. They then protect against finer
or dryer.
Fine filters and coalescing compressed air filters: remove smaller oil aerosols, water aerosols, and fine particles; for applications with higher requirements.
Activated carbon filters: for gaseous contaminants, oil vapors, odorants. Especially relevant in food industry, pharmaceuticals, and other sectors requiring very clean air.
Filter sequences: usually air treatment is composed of several steps: pre-filter → dryer → fine filter → activated carbon filter, depending on the final air quality.
JustAir offers value-added rental solutions. Some core benefits:
When you rent, you don’t just get the dryer or compressed air filters: JustAir takes care of delivery, installation, connection, and commissioning. You don’t have to worry about technical integration, piping, or electrical connections—we’ve got it covered.
We supply air handling units tailored to your required standards (ISO class, dew point, residual oil level). You choose what air quality you need, and we supply the right combination of dryer type and filter assembly.
With rentals, you pay a fixed monthly rental, without a large upfront investment. Maintenance, filter and oil parts are included, so you have no unexpected costs.
All rental units are equipped with monitoring systems for relevant parameters: dew point, pressure drop across compressed air filters, temperature, and condensate drainage. Malfunctions are detected early, ensuring the continuous operation of your compressed air systems.
Proper sizing and modern dryer technology save energy. Efficient chillers, heat exchangers and options such as variable drive or regeneration methods ensure that your air treatment is not only adequate, but also economical in use.
| Parameter | Why important |
|---|---|
| Capacity and Flow Rate (m³/min or Nm³/h) | Determines the size of the dryer or compressed air filters required; oversizing or undersizing leads to inefficiency or inadequate performance. |
| Operating Pressure (bar) | Higher pressures require compressed air filters/dryers with higher specifications and greater material strength. |
| Dew point required. | The lower the dew point, the more sensitive the process; determines whether refrigeration dryer is sufficient or adsorption dryer is required. |
| Required Air Quality and ISO Class | Residual oil, particles, and vapors: these factors determine the type of compressed air filters and the number of filtration stages. |
| Operating Time and Continuous vs. Peak | Dryers and compressed air filters are designed differently for continuous use than for intermittent use. |
| Environment and temperature | High ambient temperatures can affect operation; location (indoor/outdoor) and ventilation also play a role. |
| Maintenance Intervals and Accessibility | Compressed air filters must be replaced regularly; the condensate drain must function properly; the unit must be accessible. |
