Do You Smell Something Burning?
For safety and insurance purposes, most if not all mechanical codes have requirements with regards to fire safety for materials used in a building’s HVAC systems. For instance, the State of Ohio (USA) MechanicalCode states in the section on “Air Filters” that:Media-type and electrostatic-type air filters shall be listed and labeled. Media-type air filter shall comply with UL 900. Similarly, the Hong Kong Fire Services Department requirements for filters used in mechanical ventilating systems state that: Air filters cells (i.e. media plus media enclosure) shall be constructed from materials which conform to the fire property requirements of one of the following standards:Read More

Why choose an electrostatic, washable air filter?
When deciding what type of air conditioner or furnace filter to use, you should keep two things in mind: Airflow and Efficiency.In order to work at its optimum level, the a/c or heating unit requires no restriction to air flow. You should choose a filter that has the least effect on airflow, but removes the most dust from the air. ACI’s electrostatic air filters allow the air conditioning or heating equipment to operate at maximum efficiency while at the same time removing a high percentage of contaminants...
Expanding Reservoir Air Filters
In all vented tanks, the rise and fall of fluid levels is offset by a corresponding volume of incoming and outgoing air. Keeping the incoming replacement air clean is essential for contamination control and thus the reliability of hydraulic systems. While targeting the system`s reliability, JLM Systems Limited has developed the OilMiser™ Reservoir Aspirator (ORA) kit. This product represents a complete rethinking of reservoirs and storage tanks vented to the atmosphere. The kit builds on the unique features of...

Most of them will develop a solution meeting your needs. Below are examples of solutions you may need to consider if you are seeking for air purifier OEM solutions. In developing new OEM products, your vendor will work with you through four phases: Please note that There are two common types of air purifiers that can remove some or all of the...
Introducting a New Media for Fixed-Film Treatment in Decentralized Wastewater Systems
ABSTRACTBoth naturally occurring and artificial media have been used to treat wastewater in small community settings. Systems using naturally occurring media include sand filters and peatbased biofilters. Artificial media include open cell foam, textiles, and plastics. All the above operate as fixed-film systems, in that attached growth microorganisms are encouraged to colonize and reproduce in the media. Fixed film systems appear to produce a more consistent effluent under peaked sewage inputs and periods of no...
Biofiltration Treatment of α-Pinene
This paper provides an overview of air biofiltration with experimental data on the performance of a synthetic media biofilter system. It is shown that use of high surface area per unit volume structured media results in higher contaminant treatment rates per unit biofilter volume. It is shown that use of specially designed synthetic media allows effective control of biomass buildup by continuous removal of biomass from the biofilter media and that the biomass removal rate depends on nutrient and biocatalyst...
Contain Oil Vapor for Better Reliability
In a boiler feed pump, an air breather is used to vent the enclosed air space on the bearing housings. With increasing heat and thermal expansion, oil vapors form in the bearing housings and migrate through the air vents. The vapor then condenses in the air filter media saturating the filter with oil. The air breather becomes ineffective, which affects mechanical seals and the overall reliability. In addition, oil droplets form and run down the outside surface of the vent post, creating a slick and oily surface...
Lower Cost, Higher Environmental Performance Products: Dematerialising Furniture
Basic Information For more than a decade, industrial designer Jan Dranger carried out an enormous amount of research and development work aimed at creating a totally new concept in furniture which is comfortable, inexpensive, durable, and environmentally sound. The breakthrough came in 1993 when a solution was patented that had all the desired qualities. Seeing the commercial potential, Jan Dranger formed, together with IKEA, the development company news design DFE AB. (DFE stands for Design For Environment). Und...
Radiation Monitors and Meters
Light Description and Applications The light meter is a portable unit designed to measure visible, UV, and near-UV light in the workplace. (The CTC has a UV light meter available through its loan program, ALEP.) The light meter is capable of reading any optical unit of energy or power level if the appropriate detector has been calibrated with the meter. The spectral range of the instrument is limited only by the choice of detector. Steady-state measurements can be made from a steady-state source using the...
Controlling Bacteria In a Clean Room Environment
Maintaining the integrity of a cleanroom is a constant battle. The first step to deciding which method, or combination of methods, to employ is to identify the prime sources of contamination. There are three prime sources of contamination through which the integrity of a cleanroom might be breached. First, there is the human element. While many processes might be automated, many situations remain whereby people are essential to the process. Controlling this source of contamination is available by a variety of...
Minimising Risks to Air Quality and Regulatory Compliance With Total Filter Management
It has been shown in recent studies that as much as 25% of the total site operating budget (excluding raw material costs) for a typical medium-large dosage-form manufacturing facility will be spent on compliance measures for internal quality systems and external regulatory activities. (1) Market realities indicate that the pharmaceutical companies will need to address the overall cost of compliance if they are to remain competitive. A number of techniques have been developed to help pharmaceutical companies...
Ion Exchange Systems.
When properly applied, ion exchange for concentrated ion recovery is by far the best available technology. Where effluent streams can be filtered and ions requiring different regenerants can be segregated, ion exchange is usually the most cost effective and least capital intensive solution. We provide 4 levels of integration to cover most applications and capital budgets. The variations in the system configuration trade your labor and attention for our automation. As you invest capital, the cost of operation,...
A new Technology for Composting: Suction Aeration for Opening Composting Works
Cost-efficient solution for smell emission reduction The enormous waste quantities that are produced day by day are one of the most difficult problems for the economy as such, for cities and communities and for private households. Storage capacities for waste are scarce everywhere. Therefore solutions of all kinds that reduce waste quantities or recycle waste materials to be reused in the material cycle are top priority for all concerned. For some time now, compost production has been a widely used approach to...
Spray Painting: GT Motors
Background GT Motors (GTM) is a small panel beating and spray painting workshop established in 1964, with a current of workforce of four. GTM currently repairs and refinishes approximately 30 cars a month from a largely private and growing customer base. Like many environmentally responsible operators, the firm reuses and recycles as much of the wastes generated in their workshop as possible, and is generally receptive to ideas on how to improve its environmental and business performances. The Projects GTM...
Rolled Filters Move Filtration in a New Direction
When selecting filtration technology, industrial users have long wrestled with the tradeoffs of dirt-holding capacity versus particle selectivity or quick-and-dirty change-outs versus process time. For many applications, a self-contained rolled filter offers an effective solution to both problems. Constructed with polypropylene hardware and various media in a spiral-wound design, rolled filters create a tangential crossflow motion that sweeps particulates across the media and traps contaminants in special,...
