Engine Protection That Pays for Itself

Distributed in India by DCS Techno Services Pvt. Ltd.

DCS Techno Services is the authorized Indian distributor for Maradyne Turbo® Precleaners, the world’s leading air precleaning technology for construction, mining, agricultural, and industrial equipment.
Designed to remove dust, debris, moisture, insects, and contaminants before they reach the engine filter, Turbo Precleaners significantly extend engine life and reduce maintenance costs.

Why Turbo Precleaners Are Trusted Worldwide

Turbo Precleaners are not just raincaps—they are high-performance air-cleaning systems that use advanced centrifugal technology to deliver cleaner air to your engine.

Key Advantages

  • Extends air filter life 2 to 10 times
  • Reduces engine wear and prolongs engine life
  • Improves engine breathing for higher efficiency & power
  • Enhances turbocharger life
  • Cuts equipment downtime
  • Reduces engine overhaul costs
  • Boosts fuel efficiency
  • Increases engine oil life
  • Self-powered & self-cleaning
  • Easy installation—fits in minutes
  • Tested to SAE standards by independent labs

How Turbo Precleaners Work

Turbo® Precleaners use a high-velocity spinning action to separate contaminants from incoming air.

  1. Specially designed blades create rotational airflow.
  2. Dust, dirt, water, insects, and debris are forced outward by centrifugal force.
  3. Contaminants exit through discharge ports powered by the rotor.
  4. Only purified air enters the engine’s air filter.

This delivers cleaner air, longer engine life, and lower operating costs.

Airflow Calculation (CFM Formula)

To select the right Turbo Precleaner, calculate required airflow:

AIR (CFM) = (CID × RPM × Volumetric Efficiency) / 3456

Where:

  • CID = Cubic Inch Displacement
  • RPM = Engine Speed
  • Vol. Eff. = Volumetric Efficiency

    • Naturally aspirated engines = 0.85
    • Turbocharged aftercooled engines = 1.85

Metric conversion

  • CC (cm³) × 0.06102 = CID
  • Litres × 61.02 = CID

If the engine uses two air intakes, divide the total CFM by 2.
