Slide gates for extraction systems – precise control of air and wood shaving flows

Slide gates are essential components in extraction and dust collection systems. They enable airflows to be shut off or throttled reliably and allow extraction capacity to be directed or concentrated where it is needed.

Particularly in modular systems with multiple extraction points or filters, a well-positioned shut-off device allows flexible control of air distribution and contributes to efficient airflow regulation.

WELAfix offers a comprehensive range of slide gates in various nominal diameters – for industrial extraction systems, painting and processing lines, and wood shaving and dust conveying systems. Browse our range and buy the right slide gate for your application!

Efficient extraction with slide gates – the right version for every application

To meet the varied requirements of different systems, WELAfix offers several slide gate designs. Each version is optimised for specific operating conditions:

• Manual slide gates (HSE / HSD / HSDH): Ideal for manually controlling smaller ducts or supplementing automated systems. They are easy to install and operate – perfect for areas that need to be opened or closed manually on a regular basis.
• Chain-operated slide gates (KS): This version is ideal for elevated installation positions or remote operating points. The sliding mechanism can be operated conveniently and safely using a chain.
• Pneumatic slide gates (ADWP / ADWPS / ADWPHS / ATEX version): Pneumatically operated slide gates are ideal for automated or centrally controlled systems. They respond quickly, require no manual intervention and can be integrated into control systems – including in potentially explosive atmospheres when using the appropriate ATEX version.
• High-pressure slide gates (ADWPH): Special high-pressure models are available for applications with increased airflow or pressure. Their robust design enables them to withstand these operating loads.

The right slide gate for every extraction system – robust, corrosion-resistant and durable

Material selection is crucial to the reliability and service life of a slide gate. WELAfix primarily uses the following materials:

• Galvanised steel: This standard material offers good strength and economical manufacturing. The galvanised surface protects against corrosion in typical workshop environments and is suitable for many extraction applications.
• Stainless steel (e.g. the ADWPS version): Stainless steel offers particularly high resistance to abrasion, moisture and aggressive particles. It provides a significant quality advantage in heavily used systems or environments with high humidity.

These materials, combined with precision sealing systems using PE or elastomer seals, provide airtight closure and minimal leakage – an important factor in ensuring tightness, efficiency and energy savings in extraction systems.

Slide gates for woodworking, dust collection systems and more

• Woodworking / wood shaving extraction: Individual extraction ducts can be shut off selectively in workshops with multiple processing stations.
• Painting, grinding or polishing booths: Precise control of supply and exhaust airflows for controlled air distribution.
• Central dust collection systems: Automatic slide gate operation for load distribution and filter cleaning.
• Retrofitting or system modifications: Their modular design makes them easy to integrate into existing pipe systems.
