Hino Air Dryer for trucks
At Groupe National Hino Rive-Sud and Hino Drummondville, we know that the safety of your operations depends on reliable components. The Hino air dryer is essential to the smooth operation of your trucks’ air brake system. What does it do? To remove moisture and oil from compressed air, preventing breakdowns and ensuring optimum performance.
What is a Hino air dryer ?
The air brake system draws in ambient air, which naturally contains moisture. When compressed, this air may also contain oil from the compressor. Over the long term, these impurities can cause :
🔥 Rust in the air tanks
⛔ Clogged or blocked brake valves
❌ Power loss or brake failure
The Hino air dryer captures these impurities before they damage vital vehicle components.


Functioning and structure of the truck air dryer
Compressed air passes through various dryer components:
Moisture absorber: retains water and oil
Drain valve: evacuates residues as soon as pressure is sufficient
Oil filter: protects the dryer
Non-return valve: prevents backflow to compressor
Pressure regulator: ensures constant, safe pressure
⚠️ An automatic purge occurs during the regeneration phase to maintain filter efficiency.
⚠️ Why regularly replace Hino air dryer ?
Over time, the moisture absorber degrades:
⚡️ Less effective against humidity
🌧️ Risk of build-up in the air reservoir
❌ Risk of corrosion and internal damage to the braking system
Inadequate maintenance can lead to :
🚗 Brake valve lock
❌ Brake booster failures
🚫 Costly component replacement
⚠️ Increased risk of accidents


Inspection and recommended maintenance Hino air dryer ?
✅ Open the tank drain valve before each working day to check for water.
🔄 Replace moisture absorber periodically, even if it still appears functional
🔎 Monitor any anomalies: pressure drop, persistent humidity, irregular braking
💼 Our service centers in Boucherville and Drummondville offer complete replacement kits for Hino air dryers.
