Unique Design

MTC+ has a highly effective coalescence filter on the outlet port, which removes the fine oil and hydrocarbon particles from entering your air brake system.

  • MTC+ removes up to 40% more of the oil and hydrocarbon materials from the air stream than competitive air drying cartridges
  • Removes over 99% of contaminants from your air system, effectively eliminating oil while still maintaining its high adsorption capability
  • Eliminates oil contaminants from building up in the air system reservoirs, where they can reduce the air reservoir volume
  •  Ensures adequate air volume is available for your air brake system components downstream
  • Reduces chances of oil contaminants migrating to the air valves and other brake components, where they can impede performance
  • The canister is built to last the lifetime of the dryer resulting in fewer replacements over the life of the vehicle


The MTC+ uses a multiple-stage cleaning process to deliver the driest, cleanest air to your air brake system.

  • Provides the highest drying efficiency on the market with up to three times the drying capacity over competitive air dryers
  • Exceptional drying capacity does not impede air flow but reduces opportunities of corrosion and freezing problems
  • Low mechanical stresses, high heat and chemical resistance allow canister to last the lifetime of the dryer, resulting in fewer replacements over the life of the vehicle
  • 4-bolt slide-in and –out design allows for quick replacement while still on the vehicle
  • No hard to remove spin-on cartridges with seized threads
