Jet-Pulse filters

Self-cleaning air intake filtration engineered for low pressure drop in the dustiest environments

Description
Technical Data

In high-dust climates, traditional fixed filters can clog quickly, which leads to a loss of efficiency in turbines, engines and compressors. Burgess-Manning jet-pulse filters address this issue with an automatic self-cleaning mechanism that keeps the cartridges clean, ensuring a low and stable pressure drop throughout the filter’s lifespan. These systems are designed to withstand conditions such as sandstorms, seasonal dust like the harmattan and laterite, providing protection for gas turbines, compressors and large engines where conventional air intake filtration struggles.

A jet-pulse filter is a self-cleaning cartridge air intake filter. Instead of accumulating dust until the elements need replacement, it utilizes short bursts of compressed air that are directed back through the cartridges in an automatic sequence. This dislodges the dust, allowing it to fall away. This continuous cleaning keeps the differential pressure low and prolongs the life of the cartridges, making jet-pulse filters the preferred choice for handling high levels of dry dust.

Self-cleaning systems are also efficient in cold climate operation by reducing the risk of ice formation on the filter media. Because the cleaning occurs in place and only when needed, the system can operate for extended periods without requiring cartridge changes and avoids the steep pressure drops that typically burden fixed filters in dusty environments.

Operating Principles:

Dust-laden air is drawn through cylindrical filter cartridges. As dust builds on the cartridge surface, a controller triggers a reverse pulse of compressed air that flexes the media and releases the dust cake, which drops into a collection zone. Cartridges are cleaned in sequences so airflow is never interrupted, keeping differential pressure low and stable and protecting turbine output.

The benefit chain is the same one that drives all intake filtration, but jet-pulse manages it by removing dust continuously rather than storing it, which is why it outperforms fixed filters in heavy, dry dust.

STATIC FILTRATION OR JET-PULSE, WHICH DO I NEED?

Not sure which fits your site? See Static Filtration or talk to a Burgess-Manning engineer about your air quality and dust load.

	JET-PULSE (SELF-CLEANING)	STATIC (FIXED)
BEST FOR	High, dry dust loads like desert, sandstorm, laterite and arid sites	Moisture, salt and sticky/oily contaminants; highest final air quality
CLEANING	Automatic compressed-air pulse, in place	None; elements replaced when loaded
PRESSURE DROP	Low and stable over service life	Rises as the filter loads with dust
MAINTENANCE	Fewer changeouts in heavy dust	Scheduled element replacement

Relevant Industries

Oil and gas refineries, natural gas processing plants and LNG facilities represent remarkably intensive and acoustically challenging industrial environments, generating intense noise levels from complex processing equipment, high-pressure systems and continuous operations. Hydrocarbon processing facilities require comprehensive noise control solutions to ensure worker safety, regulatory compliance, community relations and operational efficiency.

Industrial applications generate considerable noise as a result of high-capacity machinery, continuous operations and complex infrastructure. Without proper noise control, these environments can pose risks to employee health, disrupt surrounding communities and violate environmental and occupational noise regulations. Implementing tailored noise mitigation solutions of acoustic walls, noise barriers and silencers while utilizing acoustic modeling, CFD, FEA and noise measurements to design solutions not only supports safety, but also enhances operational efficiency and community relations.

Jet-Pulse Filters FAQ

A jet-pulse filter is a self-cleaning cartridge air intake filter for turbomachinery. It fires automatic bursts of compressed air back through the cartridges to dislodge dust, keeping the pressure drop low without replacing the elements.

Intake pressure drop is a continuous power and fuel penalty. By cleaning cartridges in place, a jet-pulse filter holds a low, stable pressure drop so the turbine keeps running at peak efficiency.

Static filtration holds contaminants until the elements are replaced and gives the highest final air quality, best for moisture, salt and sticky contaminants. Jet-pulse cleans itself continuously and suits high, dry dust loads such as desert and sandstorm sites.

High-dust, dry climates like sandstorm regions, seasonal dust such as the harmattan and laterite, where a fixed filter would clog quickly.
