Dry and pure compressed air, tailored to your application.
Our extensive rental fleet includes various air handling solutions such as refrigeration dryers, adsorption dryers, combination dryers, filters and buffer tanks. Each system is plug and play, quickly deployable and tailored to your desired dew point and air quality.
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);
filters and airline filters to remove 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:
Refrigeration dryers
Refrigerate compressed air to condense water vapor. The condensate is then discharged. They deliver typical dew points of about +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 solids, dust, pollen particles, large oil aerosols. Then protect the finer filters or dryer.
Fine filters and coalescing filters: remove smaller oil aerosols, water aerosols, fine particles; for applications with higher demands.
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:
With rentals, you don’t just get the dryer or filters: JustAir takes care of delivery, installation, connection, and commissioning. You do not have to worry about technical fitting, piping or electrical connection – that is included.
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 of relevant parameters: dew point, pressure drop across filters, temperature, condensate discharge. Faults are signaled early, ensuring the continuity of your press 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 what size dryer or filters are needed, overspec or underspec lead to inefficiency or inadequate operation. |
| Working pressure (bar). | Higher pressures require filters/dryers with higher specifications and 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, vapors: determine type of filters and number of steps. |
| Use time and continuous versus peak | For continuous use, dryers/filt ers are designed differently 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. | Filters must be changed regularly; condensate drain must work properly; unit must be accessible. |
