CLEARPOINT® 3eco: High-performance compressed air filters

An important influencing factor for energy-efficient compressed air filters is the streamlined air flow in the filter. The design and materials used in the filter element ensure the lowest possible differential pressures. This results in lower energy costs with the greatest possible separation efficiency. The latest generation of the CLEARPOINT 3eco compressed air filter series has enabled us to improve our solutions for efficient compressed air filtration even more, we decreased the residual oil content by 10 times after the filter. The differential pressure can be simultaneously reduced by up to 50 % and the energy efficiency can therefore be considerably optimised. For these reasons we are very pleased to add our ECO-Label on this product.

Energy efficient and safe compressed air filtration

Taking advantage of new material and production technologies as well as a flow-optimised, corrosion-protected housing design, CLEARPOINT 3eco provides safe and reliable filtration and a qualitative, improved compressed air with considerably reduced operating costs.
The particularly high separation performance makes it possible to fulfil every compressed air filtration requirement with just 3 degrees of filtration – C (Coarse), F (Fine) and S (Ultra-fine). The new 3eco-filter has of course also been validated by the independent IUTA Institute according to ISO 12500.

What makes filtration expensive? Operating costs make up the largest part of the cost of a compressed air system. This includes the energy costs for the compressor. To keep these costs as low as possible, the differential pressure must be as low as possible. With their innovative filter elements, CLEARPOINT eco compressed air filters offer enormous savings potential.

Filter elements with low differential pressure reduce operating costs

In compressed air treatment, the greatest savings potential lies in the reduction of energy costs. Depending on the utilisation of the system, these can amount to up to 80% of the total costs. The energy consumption is significantly influenced by the differential pressure during the filtration of oil aerosols and particles.

The new CLEARPOINT 3eco filters reduce the operating costs even further compared to the already good CLEARPOINT 3E filters. The energy savings per year are in some cases higher than the purchase costs of the filter elements. And with their oil aerosol separation efficiency of up to 99.95 %, they even increase process reliability.

The graph shows the differences in differential pressure for filters with filtration grade S in size S040 with energy-optimised volume flow.

Filter elements with innovative design

The considerable increase in the performance of the filter elements was made possible by new materials: the new pleating technology (soft pleat) uses the entire filter surface and thus enables higher separation efficiencies at lower differential pressures than conventional pleating technology, in which the pleating tips are coated with an adhesive. The open plastic support fleece (2) keeps the pleated filter material (4) in shape without reducing the filter area. The finest glass fibres in combination with the large filter volume lead to optimum flow velocities in the filter medium and support efficient depth filtration for consistently high separation rates.

  • The optimal transition from the filter medium to the drainage layer (3) is always ensured, as the drainage layer lies protected behind the outer support cylinder.
  • Oil- and water-repellent fibre coating leads to optimum transport of the liquid particles through the filter medium.
  • Inner (5) and outer (1) stainless steel support cylinder protect the filter element in case of pressure fluctuations.

Function of compressed air filters

Coalescing filters combine different filtration techniques.
In surface filtration, larger particles are trapped in a fleece by sieving effect. In depth filtration (or impact separation), solid particles and aerosols penetrate deeper into the filter bed, lose their kinetic energy, slow down and stick to fibres. In the depth of the filter bed, aerosols collide with the fibres due to Brownian molecular motion, migrate along the fibres in the direction of flow of the compressed air and form larger droplets. These collect in the drainage layer and reach the condensate discharge by gravity.

Types of filters

All filters consist of a filter housing and a filter element. Depending on the structural conditions and the respective volume flow, the filter housings are connected to the pipeline via a thread or flange filter.  
Threaded filters
Threaded filters are integrated directly into the compressed air line. This can be done directly after the compressor or at the branch of a separate supply line or directly before an application. Often several thread filters are combined to achieve the desired specification step by step via step filtration. Threaded filters are available for a wide range of pressure stages. 
Flange filter
Flange filters are used for particularly large volume flows and correspondingly large compressed air lines. They are connected to the compressed air line by a flange and can be mounted on the wall or on the floor. Here, too, there are different filtration degrees and pressure stages.
