The new REVEX® HEPA filter

Excerpt from Wikipedia:

“Filters meeting the HEPA standard have many applications, including use in medical facilities, automobiles, aircraft and homes. The filter must satisfy certain standards of efficiency. To qualify as HEPA by US government standards, an air filter must remove 99.97% of particles that have a size of 0.3 µm. The original HEPA filter was designed in the 1940s and was used in the Manhattan Project to prevent the spread of airborne radioactive contaminants. Over the decades filters have evolved to satisfy the higher and higher demands for air quality in various high technology industries, such as aerospace, pharmaceutical drug processing, hospitals, health care, nuclear fuels, nuclear power, and integrated circuit fabrication.”

Such HEPA filter should be used for application like the filtration of dry smoke particle at EDM applications. To use such HEPA filters in the exhaust of liquid coolants from machinery centers is not recommended. For such applications we recommend to use the special designed filter for liquid aerosols – the REVEX®-HEPA filter.

REVEX®-HEPA filter are designed for the removal of liquid mists, fogs and for wet super fine aerosols. The REVEX®-HEPA filter are self cleaning, which means that condensing mists and oils are released by gravity. Therefore the filter needs to be installed horizontal.

Technical data:

Initial-∆P [Pa]: 250 Pa, Max. temp. [°C]: 80°C, Filtermedia: glass fibre fleece, Prices and sizes same like the actual REVEN® H13 HEPA smoke filter. For installation and retrofit for all REVEN® X-CYCLONE® HEPA top filter covers.

Air cleaner with pure competence in air! Check what Warren Buffett said…

A quote from Warren Buffett: „The most important thing in terms of your circle of competence is not how large the area of it is, but how well you have defined the perimeter.“ Therefore check our new air cleaning info files, our circle is set by pure competence in air.

Oil mist separator on machine tool – demand control XSC system saves energy


In order to prevent the production site from being polluted with oil mist, oil mist separators suck the coolant fumes from the working area of ​​the machine tools. Often, the separators run at full capacity, regardless of the current requirements. The consumption of energy and coolants is therefore unnecessarily high.

As an alternative to conventional on / off control, Rentschler Reven now offers the digital power controller XSC (X-Cyclone Speed Control), whose sensor technology measures the machining activity of the machine tool. An intelligent control unit adjusts the suction power continuously via ventilation valves and an optional frequency converter with a micro computer and algorithms. The aerosol separator communicates with the machine. Its power consumption can be halved and thanks to a patented Venturi ventilation and condensation system, the separation efficiency can be increased up to 50%. Furthermore the XSC system extends the maintenance intervals for filter cleaning and also the filter service life.

A pressure and flow sensor also detects the door state of the machine. If the door is opened, the suction power rises and ensures a stable vacuum in the work area of the machine tool. This prevents coolants particles from leaving the machine. The XSC control can be retrofitted with all encapsulated machine tools; Controllers and sensors are installed within a few hours, and thanks to the modern frequency inverter, the operating condition of the oil mist separator can be transferred online to an existing building control system. 


Kitchen ventilation – RSC (Reven Speed ​​Control) saves energy

In order to improve the cost-effectiveness of ventilation in large kitchens, Rentschler REVEN provides the intelligent fan speed control system RSC, whose microprocessor adjusts the speed of the supply- and exhaust fan variable to the cooking activity. Temperature and humidity sensors, adapted to the conditions of commercial large kitchens, recognise the cooking activity; the controller then drives the supply and exhaust air up or down, and at the same time, the required air volumes are moved into various cooking zones via ventilation flaps. This saves energy, prolongs the service life of downstream air cleaners and avoids uncomfortable air draft. A case study: A large commercial kitchen in southern Germany has a ventilation system with an air volume of 20,000m³/h. It causes energy costs for fans, cooling and heating of approximately 60,000 Euros per year. A required RSC ventilation control halves these costs! For more information, visit and

Dirty exhaust air Not In My Back Yard


Who wants to wake up to know that there are restaurants, residential buildings, or mechanical workshops will be built across the street? Would the community’s reaction change if the prospective projects changed to hazardous waste facility, incinerators, garbage dumps, or infectious disease hospital? A common reaction would be “Not In My Back Yard”, or NIMBY.

Dr. Iyad Al-Attar discusses why air filtration considerations should be included in the decision-making process.
