Tubular Pulse Filters

The system’s features include ladders and access platforms that exceed Australian occupational health and safety standards, with all serviceable items accessible from a top platform free of trip hazards. The compressed air system also includes a self-bleeding lockout ball valve for added safety.

Mideco’s Tubular Pulse Filters are designed for straightforward servicing, featuring a no-tools rebag system that helps minimise downtime during refurbishment and maintenance activities.

Offering flexibility across a range of applications, the Tubular Pulse filter range accommodates various inlet and outlet sizes and positions, bag fabrics, mounting structures, and casing materials. The baghouses can be configured as standalone units or in a cellular setup, allowing individual cells to be taken offline for cleaning or maintenance without disrupting the entire system.

A pulse jet dust collector, also known as a baghouse, is a filtration system that removes dust from an air stream by drawing it through a bank of vertical filter bags. 

Mideco’s Tubular Pulse Filters are engineered pulse jet dust collectors designed around optimal air handling, superior filter cleaning, and excellent collection efficiency. The range prioritises personnel safety, ease of maintenance, and long-term performance through durable filter design and simplified servicing requirements.

Built to minimise ongoing ownership costs, Tubular Pulse Filters deliver reliable dust collection with reduced maintenance complexity and extended filter life.

As air passes through each bag, dust collects on the outside of the fabric while clean air continues through to the outlet. A periodic reverse pulse of compressed air is fired down through each bag in sequence, dislodging the collected dust cake from the fabric without stopping airflow to the rest of the system. The dislodged dust drops into a hopper below for removal, and the bag returns to service immediately. 

Pulse jet dust collectors are suited to industrial applications where reliable filtration and consistent airflow are required. They are best suited to fine dust and manageable coarse particles that will not damage filter bags.

Before selecting a system, dust type and particle size should be assessed to confirm suitability. Where heavier or more abrasive particulate is present, a Mideclone can be used as a pre-cleaner to remove larger particles before filtration, helping protect the downstream dust collector.

Mideco’s Tubular Pulse Filters have been applied across industries including:

• Construction, where material processing and handling generate airborne dust
• Manufacturing, where production processes require reliable dust filtration
• Recycled waste processing and management, where mixed material streams can create complex dust loads

Beyond these applications, Tubular Pulse Filters can also be engineered for a wide range of dust collection requirements, depending on the material type, particle characteristics, and operating conditions.

Suitable applications include:

• Cement and concrete processing
• Grain, feed, and wheat handling
• Chemicals and fertilisers
• Mining and mineral processing
• Quarrying
• Timber processing
• Plaster, powders, and flour applications
• Extreme fine particulate, such as carbon black
• Silo vent filtration applications
• Food processing environments

Each application requires assessment of dust type, particle size, and system requirements to determine the most appropriate filtration solution.

Mideco’s Tubular Pulse Filter solutions have been applied across industrial dust environments, including projects for Boral and SKM Recycling in Victoria. Explore the Tubular Pulse Filter Solution for Boral and the Tubular Pulse Dust Collector Solution for SKM Recycling in Victoria case studies to see how the technology has been implemented for specific dust collection requirements.

Tubular Pulse Filters and Economy Filters for compact dust collection are both pulse-cleaned baghouse collectors, but they suit different scales of operation. Economy Filters are designed to maximise filter cloth area within a minimal footprint, making them well suited to smaller installations, bin vent applications and sites where space is limited. 

Tubular Pulse Filters are designed for larger projects and sites requiring superior filtration and efficient dust collection, providing a scalable dust collection solution for facilities with greater dust management requirements. Their configuration flexibility allows systems to be tailored to the scale and layout of the project, including standalone or cellular setups where appropriate. 

For smaller sites or more compact dust collection requirements, Economy Filters provide a practical, space-efficient alternative. The key distinction is project scale: Tubular Pulse Filters are suited to larger dust collection projects, while Economy Filters are the more compact option.
