Frequently Asked Questions (FAQs)
1. Why do compressed air tanks drain?
Compressed air tanks are drained to remove condensation. This helps prevent corrosion and damage to the compressor, extending its lifespan. It also reduces wear on tools and equipment powered by the compressor.
2. How does an air compressor drain work?
An air compressor drain works by allowing condensate to flow into a reservoir. When the liquid reaches a certain level, a float lifts off the seats, sending control air pressure to a pneumatic piston. This opens a ¾ ported ball valve, allowing the condensate to be drained.
3. What happens if you don't drain your air compressor?
If you don't drain your air compressor, the water vapor in the atmospheric air that fills the tank can accumulate and damage the internal structure of the compressor. Regular draining helps prevent this accumulation and maintain the compressor's performance and longevity.
4. What happens if you don't drain your air tanks?
If air tanks are not drained, water can build up and the compressor could push out water droplets. This can lead to the water picking up dust and residue, causing further damage to the tank and its components. Regular draining helps prevent this and keeps the tanks in good condition.
