Safer, Healthier & More Productive…

…and CLEANER! Air System Products, along with the entire Filtration Group organization is committed to making the world a Safer, Healthier, & More Productive, but we are taking it up a notch and doing our part to make it Cleaner & Greener as well. Along with our new initiative to lessen the impact of paper waste by providing a scan-able QR Code instead of shipping a printed Installation and Operation Manual on our Robo-Drain line of condensate drains, ASP’s zero-loss drains and oil/water separator systems help reduce facility energy cost and keeps oil from leaching into the groundwater.

Compressed air is one of the most costly utilities in any manufacturing facility, and with our complete line of pneumatic and electronic zero-loss drains, ASP can help you save energy from escaping with every cycle of the drain. Our Zero-Loss Robo-Drain alone will save our combined customer base an estimated $900,000 in energy consumption costs in 2022.

The Environmental Protection Agency (EPA) classifies spent oil as a pollutant and imposes limits on the amount of oil that can be expelled by air compressors. This is defined as 15 parts per million (15/ppm), although any level that generates a sheen on the surface of water qualifies. This is true of the runoff that many compressors dump into their drainage systems. ASP oil/water separators are made up of proprietary particles that attract oil and adhere it to a filtering bed, lowering the amount of oil in the runoff to acceptable limits. In fact, in 2022 alone, our Posi-Zorb Oil/Water Separator System, water with our proprietary adsorption media will prevent an estimated 701 gallons of oil from seeping into the ground.

As you can see, Safer, Healthier & More Productive isn’t just what we say, it’s what we do.

Essential Periodic Media Replacement

It is important that media is changed out routinely. Left unchecked, saturated media will permit untreated condensate downstream and may cause the unit to overflow. Although upsets occur more naturally with a gravity fed systems, even with a pump module, the pump can allow oil to bypass the media which could cause the system to exceed the local regulatory limits. Collaborating with condensate management experts at ASP can help ensure the right Oil Water Separator with the proper media maintenance plan is being used in any application.

For some products, such as ASP’s Posi-Zorb product line, the media module is self-contained which controls the possibility of spills or contamination during media replacement. These are just two of the features that many operational facilities prefer as they are low maintenance and cleaner as the condensate is well-contained. It is important to understand that regular maintenance is crucial to keep the system running at its top performance. If the media becomes saturated, there is a risk of by-passing or overflow of untreated condensate which is not only bad for your system but bad for the environment. To avoid this, a periodic replacement of the media is imperative.

Changing your media is surprisingly simple. Whether you’re utilizing our Accu-Sep, Accu-Zorb, or Posi-Zorb OWS system, the process to change out the media is just a few short and simple steps. Click the links below to find a photo-guided step by step guide for your system.

ASP continues to experience raw material price surges and costly supply chain interruptions that has resulted in the need to raise our prices. Please find the attached new price list that is effective July 1, 2022.

In addition to this price increase being applied to new orders, we must apply the new price to any open orders in our system. We are working incredibly hard on cutting down our backlog to minimize the number of open orders this will affect. We have already made great strides in reducing our overdue backlog by 50% in the last couple months, and will continue to do whatever we can to reduce it moving forward.

We appreciate your past business, our partnership, and stand ready to support your efforts to grow your business in the new year. 

New prices are effective July 1st.

Efficient Components = Efficient Systems = Government Rebates!

Manufacturers and consumers alike are becoming increasingly concerned about energy efficiency. When investing in new capital more and more businesses are looking towards energy efficient equipment because of two main reasons. First, energy-efficient equipment can reduce utility costs, ultimately saving business’s money. Next, energy-efficient systems add less strain our natural resources, thus saving them for future use and reducing climate change.

Not only are companies making these energy saving decisions, but the federal and state government are encouraging this practice as well. How? Well DSIRE is a highly useful research tool that enables location-specific searches for state-level energy-efficient incentives. You can get a comprehensive list of all the programs that are accessible to you by simply entering your zip code or selecting a state. When you find an incentive you like, click on it for more information about how to take advantage of the benefit in question. With these incentive programs our Electric and Pnuematic Zero Loss Drains are even more of a perfect fit to helo save your company money and energy!

Relative Humidity, Dew Point & How it Affects Your Compressed Air System

The temperature at which water transforms from a vapor to a liquid at a specific pressure is known as the DEW POINT. The dew point decreases as the air becomes drier.

The amount of water vapor in the air compared to the maximum amount it can contain is determined by the RELATIVE HUMIDITY. Temperature and pressure both affect relative humidity. At greater pressures compared to lower pressures and warmer temperatures, air may contain more water vapor.

The dew point is an essential aspect of the purity of compressed air. It indicates the amount of moisture in the air. If the dew point is too high, meaning there is too much moisture in the compressed air system, it can cause issues with the system, the instruments and equipment that use the air, as well as the quality of the product or process. If your air must conform to ISO purity standards, a dew point that is too high may also place you out of compliance. To protect your system, prevent problems with air-using instruments, and maintain product quality, ensure that your pressure dew point falls within the application-specific parameters.

Excessive condensation in compressed air systems can result in a variety of issues for the compressed air system. Some examples include:

Corrosion and/or Rust:
Moisture causes metallic items, such as compressor parts, pipe systems used for distribution, and tools and equipment that require compressed air, to corrode.

When temperatures drop, extra moisture that builds up in control lines, valves, and hoses is susceptible to freezing. As a result of water expanding when it freezes, equipment may become harmed.

Control issues:
Instruments for air compressors may get obstructed or give erroneous readings as a result of water and corrosion in control lines.

Lubrication Issues:
Rust and water in the compressor or air tools will reduce lubrication effectiveness and cause moving components to be damaged.

Compliance Issues: If your compressed air purity must fulfill ISO 8573 criteria, too much moisture in the air will put you out of compliance.

One of the efficient and cost effective ways to help combat moisture in your compressed air system is by the use of an Air System Products condensate drain. Whether you need a simple electronic timer drain, or an on-demand zero-drain, ASP has you covered.
