Types of Spray Booth Filter

Types of Spray Booth Filter

Spray booths rely on efficient air filtration to maintain a clean, safe, and high-performance environment. At the core of this process are two types of filters:

  • Input Filters – Clean incoming air by removing dust and other contaminants before it enters the spray booth or prep area.

  • Extraction Filters – Capture particles added to the air inside the booth, such as paint, glue, or dust, before they exit the system.

Here’s a detailed look at the types of filters we offer and how they serve different spray booth needs.


Procart Filters – High-Performance Extraction Filtration

Procart filters are multi-layered cardboard filters designed specifically for extraction. They’re built to capture a wide range of particles - paint overspray, glue mist, dust - while maintaining optimal airflow within the booth.

Key Features:

  • High holding capacity for waste particles

  • Maintains consistent airflow to increase filter lifespan

  • Compatible with all types of paints and coatings

  • Suitable for most spray booth designs

Specialised Options:

  • Procart H, M2, and KH: Equipped with an extra fibre layer for improved performance with light or dry particles like powders.

  • Ideal for booths with higher-than-recommended airflow or limited spraying distances.

  • Procart I: A non-flammable variant, ideal for environments requiring additional fire safety.


Media & Glass Fibre Filters – Versatile Input and Extraction Use

These filters come in various materials, typically glass fibre or woven synthetic fibre, and are suitable for both input and extraction tasks.

Options in This Range:

  • Profibre: General-purpose extraction filter.

  • Propora: Specially formulated to trap water-based paint particles.

  • Progiallo: Impregnated with gel to trap coarse dust and overspray, offering higher holding capacity.


Woven Synthetic Rolls – High-Quality Input Filtration

While suitable for both input and extraction, the Protop range is designed specifically for input filtration where ultra-clean air is required for high-quality surface finishes.


Panel Filters – Flexible and Widely Applicable

Panel filters are available in two main styles - fibreglass and pleated - and come in a variety of thicknesses and sizes.

Panel Types:

  • Fibreglass Panels:

    • Best for extraction use only.

    • Fibre structure is too loose for effective input filtration.

  • Pleated Panels:

    • Can be used for both input and extraction.

    • More often used as secondary filters, rather than the primary extraction barrier.

  • Carbon Pleated Panels:

    • Provide odour and fume absorption, suitable for input or extraction.

  • Finepleat Polypropylene Panels:

    • Great for removing moisture from intake air.

  • Frame Materials:

    • Standard: Cardboard

    • Optional: Galvanised metal for more durability (especially in pleated designs)


HEPA Filters – Maximum Air Purity

HEPA (High-Efficiency Particulate Air) filters are the gold standard in air purification, used in medical, healthcare, and cleanroom environments.

Benefits:

  • Removes at least 99.97% of airborne particles

  • Captures dust, bacteria, fungi, viruses, and other fine contaminants

  • Ideal for industries where sterile conditions are required


Laminar & Turbulent Flow Filters – Precision Airflow Control

Available in wooden or galvanised frames, these filters are essential for managing the airflow pattern inside the booth.

  • Laminar Flow Filters:

    • Slimmer design

    • Produces smooth, controlled airflow for precision coating applications

  • Turbulent Flow Filters:

    • Thicker frame for higher airflow rates

    • Suitable for larger or high-throughput spray booths

  • HEPA Deep Pleated Filters:

    • Maximum filtration performance

    • Used in sterile or ultra-clean environments like hospitals and high-grade manufacturing


Choosing the Right Filter for Your Spray Booth

The right filter depends on your booth’s purpose, airflow design, and the types of materials you work with. Here’s a quick guide:
