The CFT RAM 4×4 Pre-Filter is a high-efficiency pre-filtration system designed for light-duty vehicles (LDVs) operating in dusty mining environments.
Engineered to integrate with Safari snorkel inlet systems, this aerodynamically designed unit reduces airborne contaminants before they reach the primary air filter – helping extend filter life and improve overall engine performance.

Mining environments are extremely dusty, placing significant strain on engine air filtration systems.
In field testing under very dusty conditions:
This demonstrates a significant reduction in dust loading and maintenance frequency.
Read the full case study here.
By reducing the dust load entering the engine’s air filtration system by 8–10 times, the pre-filter helps minimise:
This results in improved operational efficiency and lower overall running costs for mining fleets.

Inside the unit is a cassette system consisting of aluminium plates, a central shroud, and a dust collection bowl. The cassette contains either 16 or 30 axial cyclone tubes, each made up of a:
As air is drawn through the snorkel and pre-filter:
With an average efficiency of 93% (based on SAE Coarse dust), the system significantly reduces the load on the primary air filter.
Please note: The snorkel is not supplied – only the pre-filter unit.
The RAM 4×4 Pre-Filter has no moving parts, reducing wear and maintenance requirements.
Routine maintenance involves:

A pre-filter removes larger dust particles and a significant portion of airborne impurities before the air reaches the vehicle’s main air filter. The primary air filter then performs the final stage of filtration. By reducing the amount of dust reaching the air filter, the pre-filter helps extend its service life and maintain engine performance.
No, the RAM 4×4 Pre-Filter is not a replacement for the vehicle’s primary air filter. It is installed before the air filter on the snorkel inlet and works to remove airborne contaminants before they reach the standard air filter. The original air filter remains in place and continues to perform its filtration role.
By removing up to 93% of airborne impurities before they reach the air filter, the RAM 4×4 Pre-Filter significantly reduces dust loading. This means fewer air filter replacements, less maintenance downtime, and improved efficiency in dusty mining environments.
