WAMAIR Spot polyTUBE: Dust Filtration Without Compressed Air

Dust control should not add unnecessary complexity to a bulk solids handling plant.

At conveyors, transfer points and process equipment, capturing dust close to its source helps keep material within the process and limits the need for extensive centralised extraction systems. Yet conventional filter cleaning can introduce an additional requirement: compressed air.

That means pneumatic lines and components, energy to generate compressed air and additional equipment to maintain. Moisture, condensation and low temperatures can introduce further operating challenges.

WAMAIR Spot polyTUBE takes a different approach. It combines compact polyTUBE filter elements with an electrically driven mechanical cleaning system that operates without compressed air.

The result is a local dust filtration solution designed to save energy, installation space and maintenance effort, while simplifying plant integration.

Capture dust where it is generated

WAMAIR Spot polyTUBE is designed for installation directly on bulk solids handling and processing equipment.

Rather than extracting dust through extensive ductwork to a remote collection point, the filter captures airborne particles locally. Separated material is then returned directly to the process.

For plant operators, this approach can simplify dust control infrastructure and reduce the space needed for filtration, particularly at conveyors, transfer points and other areas where installation space is limited.

It also makes the filter particularly relevant for applications where providing compressed air would be difficult or costly.

More filtration surface in less space

The polyTUBE filter element is central to the compact design.

Its open-profile tubular cell structure provides a large effective filtration surface within a comparatively small volume. The filter geometry and media are also designed to limit residual dust retention, supporting effective cleaning and stable filtration performance.

According to WAMGROUP technical data, polyTUBE offers approximately four times the performance of conventional filter elements.*

The elements are installed vertically inside a stainless-steel casing. Their reduced height helps minimise the overall footprint and facilitates installation where headroom is restricted.

For maintenance teams, compact dimensions also mean easier handling when filter elements need to be inspected or replaced.

Eliminate compressed air from filter cleaning

The key difference is what happens during cleaning.

Instead of pneumatic pulse-jet cleaning, WAMAIR Spot polyTUBE uses a patented electrically driven pulse mechanical cleaning system.

The mechanism acts on an energy distribution plate, transferring the cleaning action to the filter elements and detaching accumulated dust. The collected material then falls directly back into the process.

No compressed-air supply is required.

This removes the need for dedicated pneumatic lines and related components and eliminates the compressed-air consumption normally associated with filter cleaning.

For a new installation, that can mean simpler plant integration. For an existing plant, it removes an auxiliary utility from the filtration process.

Less energy. Less noise.

The benefits can also be measured at the cleaning system itself.

WAMGROUP technical data indicate:

• annual cleaning-system energy consumption below 100 kWh;*
• noise during cleaning approximately 9 dB(A) lower than the referenced conventional pneumatic pulse-jet system.*

These figures make the mechanical cleaning principle particularly relevant where auxiliary energy consumption or filter-cleaning noise are important considerations.

Designed to reduce maintenance effort

Reducing operating complexity is not only about eliminating compressed air.

WAMAIR Spot polyTUBE has been designed to make routine access straightforward. The compact filter elements can be removed without tools, while a lockable quick-release system and gas spring provide access through the weather-protection cover.

This can reduce the number of steps involved in routine inspection and filter servicing, particularly where access around the equipment is restricted.

Monitor filter condition and optimise cleaning

The filter incorporates the FILMEC electronic controller to manage operation and monitor key parameters.

Differential pressure monitoring provides visibility of filter condition, while USB recording supports operating-data collection. MODBUS communication enables integration with compatible plant control systems.

This allows cleaning to be managed according to operating conditions while giving plant personnel greater visibility of filtration performance.

Filter media, cleaning system, fan and electronic control are therefore designed as one integrated filtration package rather than as separate plant components.

Focus on what the plant actually needs

For operators, the value of WAMAIR Spot polyTUBE comes from removing complexity as much as from adding filtration technology.

No compressed air means no pneumatic supply dedicated to filter cleaning and no associated compressed-air energy consumption.

Compact polyTUBE elements provide a large filtration surface in a small installation envelope.

Integrated control and maintenance-friendly access help simplify day-to-day operation.

Together, these characteristics make WAMAIR Spot polyTUBE a practical option for bulk solids handling and processing applications where plant operators need effective local dust control without the infrastructure and operating requirements of compressed-air cleaning.

Capture dust at source. Clean mechanically. Eliminate compressed air.
