Active Particulate Filters

Active Regeneration System - Reducing PM by up to 95%

Part of the Pyroban Envirosafe Active Regeneration range, Acti-Trap™-F is an exhaust particulate filter system with Active Regeneration, allowing for automatic cleaning of the exhaust filter.

Acti-Trap-F is designed for diesel powered equipment commonly operating on challenging cycles and can also be used on engines that do not run on ultra low sulphur diesel (ULSD). This includes, off-highway equipment such as forklift trucks, construction equipment and mobile generators.

Acti-Trap-F can remove up to 95% of Particulate Matter (PM) from the exhaust gas and can be supplied with an optional oxidation catalyst, allowing further emission reductions in Hydrocarbons and Carbon Monoxide by up to 95%.

How it Works

Acti-Trap-F is comprised of three primary components; the FBC catalyst dosing system, Satacen 3 and a SiC wall flow filter monitored by a sophisticated electronic control unit (ECU).

The Satacen 3 additive, stored in a separate on-board tank, is dosed in precise amounts into the main fuel supply. The FBC additive binds itself to the PM as it is formed during the combustion cycle while any excess additive is returned into the main fuel tank.

The Silicon Carbide wall-flow filter traps PM once it has been catalysed with the Satacen 3 FBC. The particulate is then oxidised within the system filter which is extremely durable, withstanding high regeneration temperatures.

How Acti-Trap-F Works The active regeneration system is based on a programmable control unit that can be optimised to the engine’s duty cycle to ensure a robust filter performance.
