Pulse Jet Collectors

Pulse jet baghouse dust collectors are used when it is impractical to shut down your dust collector to clean the bags. A pulse of compressed air is blasted through the bags to blow loose the built up particles on the bags to maintain optimum filtration efficiency.

Modular Pulse Jet Dust Collector

Fully assembled Mikro-Pulsaire™ pulse jet dust collectors are ideal for applications requiring filter media area generally between 151 - 8,246 ft² (14 m² - 766 m²)

Multi-Modular Pulse Jet Dust Collectors

For large applications, generally greater than 4,500 ft2 (440 m2) media area, pulse jet baghouse / collectors are provided in prewired sections sized to suit shipping limitations

Round Pulse Jet Dust Collectors

Nederman MikroPul's round pulse jet dust collectors are for high vacuum or high pressure applications.

Flat Bag Pulse Jet Filters

Fully assembled horzontal Nederman Mikropul pulse jet dust collectors, with filter area from 110m² - 2300m².

Long Bags for Baghouses

Our long bag technology for baghouse dust collectors allows for less dust loading, eliminates dust re-entrainment, and provides fewer and less violent cleaning cycles with lower compressed air usage.

How does a pulse-jet dust collector work?

Filtering - normal operation

Dusty air enters pre-sep horizontally
Decelerates, separates heavier coarse particles, turns toward bags (bags shielded from direct abrasion)
Heavy coarse dust falls down directly into hopper
Air passes through bag material and dust retained on bag surface
Filtered air blown out by fan
Dust finally is being removed by discharge device

A pulse jet dust collector is a dry filtration system that incorporates an integral media cleaning system. It might be called a pulse-jet collector, a pulse-jet filter or a pulse-jet fabric filter. The media is usually a tubular shaped vertical bag of varying diameter and length. It’s also common to see pleated bags and “flat” bags mounted horizontally. Many bags are arranged inside a housing and particulate matter accumulates on the outside of the bags.

The cleaning system removes particulate that has accumulated into a “cake” onto the bags by blowing high pressure compressed air into the inside of the bag. Nederman MikroPul is proud to be the home of the original Pulse-jet cleaning patent, granted in 1957.

Pulse jet bag filters are a common type of dry air pollution control equipment found in industrial plants and play a critical role in the protection of workers, the general environment and also to collect valuable material for refining or re-use.

Automated cleaning control systems have become common to regulate the pulse of compressed air that the bags receive. Cleaning strategy and correct operation of the cleaning system yields improvements in the use of compressed air and therefore energy use. Bag life has been shown to improve through good maintenance practices in pulse-jet dust collectors.

What are some of the benefits of pulse-jet dust collectors?

The technology can be applied across many different gas or dust types
The mechanisms are relatively simple to install and maintain
This system has become accepted practice across many industries, bringing familiarity
Pollution control is very good and can be further enhanced by design

What are some constraints for using pulse-jet dust collectors and filters?

There must be a reliable compressed air source
Sizing of systems for airflow should be precisely calculated and re-assessed as process conditions change
Regular maintenance of the bags and cleaning system enhance lifecycle performance
Care taken to manage inlet air flow and temperature increases asset life
