National Filters

Heat is the enemy of pure air. 🌡️
Did you know that Activated Carbon filters lose almost all their effectiveness if the air is too hot?
If your aftercooler is failing and the air hitting your activated carbon filters is above 45°C, that "Class 0" air you're paying for is likely contaminated with oil vapour.
The Fix:
Ensure your dryer and aftercooler are serviced before summer hits. Keep that air cool, and your filtration will do its job.
