Will Expel compressed air filters save my site money?
Yes! Expel filters are specifically designed to reduce operating costs by improving the efficiency and longevity of your pneumatic equipment. Traditional compressed air preparation methods cannot guarantee equipment protection, often leaving critical machinery vulnerable to costly downtime and repairs.
Here’s how Expel can save you money:
- Zero Consumables: Unlike traditional filters, Expel doesn’t require disposable internal elements, reducing ongoing costs.
- Longer Equipment Life: Expel protects your pneumatic equipment against three primary sources of compressed air contamination. It continually removes 99.999% of liquid water, oil emulsion fluids, and solid particulates down to 1 micron.
- Reduced Maintenance Costs: By eliminating compressed air contamination, Expel prevents wear and tear on your equipment, lowering repair bills.
- Energy Savings: Conventional filters retain compressed air contaminants, forcing your air compressor to work harder and use more energy. Expel’s energy-efficient design instantly discharges contaminants from the filter, saving energy.
Why is Expel different from a traditional compressed air filter?
Traditional compressed air filters rely on disposable internal elements made from mesh or sponges that trap contaminants. These elements become less effective over time and cannot guarantee the protection of pneumatic equipment.
We designed the Expel filter range using Computational Fluid Dynamics (CFD) to find the most effective contaminant filtering method. Instead of trapping contaminants, Expel uses physics to separate impurities and discharge them through the base of the filter. Expel guarantees clean and dry air without the need to replace internal elements.
I have a compressed air dryer. Do I need Expel filters?
Yes. We regularly visit sites where moisture appears after an air dryer, leaving critical pneumatic equipment vulnerable to contamination and damage. Expel is the ultimate failsafe, protecting pneumatic equipment against liquid water, oil emulsion fluids, and solid particulates, even if your dryer fails.
Can I use Expel filters instead of a compressed air dryer?
Sometimes, yes. Several sites have decommissioned refrigerant dryers and now use Expel as their sole compressed air preparation method. However, this depends on several factors, including your site setup. Contact our sales team to find out if Expel can replace your dryer(s).
Iām not experiencing issues with compressed air contamination. Do I need Expel filters?
Yes. Compressed air contamination is often unseen until it causes damage to pneumatic equipment. Damaged pneumatic equipment leads to problems, including unplanned maintenance, increased operational costs, and higher energy consumption. Expel filters stop these issues, extending the life of pneumatic equipment and reducing the total cost of ownership.
Where can I buy Expel?
You can purchase Expel directly from Original AVG by calling +44 (0)345 50 50 222 or emailing sales@originalavg.com.
