BAG HOUSE FILTERS

Pulse-jet filter bag cleaning. Automated compressed-air pulses maintain filtration efficiency without stopping production, reducing bag blockage risk and extending service intervals between bag replacements.

Particulate emission control to EU standards. Ammann baghouse filters meet EU Industrial Emissions Directive thresholds and equivalent international environmental standards for asphalt plant operations.

Filler recovery and return to process. Captured mineral dust is collected and returned to the mixing process as recovered filler, reducing raw filler purchases and eliminating solid waste from plant operations.

High-efficiency filtration fabric. Filter bags are selected for the operating temperature range, chemical resistance to bitumen fumes and moisture, and the filtration efficiency required to match plant exhaust conditions.

Modular housing design for capacity expansion. Filter modules can be added if plant throughput increases, protecting the initial investment and avoiding full system replacement when upgrading to higher capacity.

Anti-condensation insulation. Thermal insulation on the filter housing prevents exhaust gas temperature dropping below the dew point, protecting filter bags from condensation damage during operation and at plant start-up.

as1 integration for pressure differential monitoring. Filter differential pressure is monitored in real time via the as1 control system, alerting operators to bag degradation before filtration performance is affected.

Global spare parts and service support. Filter bags, pulse valves, and housing components are available through Ammann's service network, with on-site support for bag replacement and re-commissioning.
