Overview

The Air Slide Sampler (AS) is engineered for continuous or intermittent sampling of dry, free-flowing, non-sticky powdered materials transported through horizontal or inclined air slides. Ideal for industrial bulk material handling systems, the AS enables reliable increment extraction from airborne material flows.

This sampler is designed to intersect the ducted powder flow—typically contained within a circular cross-section duct—to collect linear, representative sample increments across the material stream. Its precise positioning and design ensure accurate and consistent sampling during pneumatic conveying processes.

Features

Air Slide Sampler (AS)

The Air Slide Sampler (AS) collects a small quantity of material per rotation, enabling continuous sampling over a set time period to generate accurate and representative average samples.
The AS is designed to maintain uninterrupted material flow within the air slide. Its non-intrusive construction ensures efficient operation without affecting conveying performance.
By replacing manual grab sampling, the AS offers a fully automated solution, reducing labour, minimizing safety risks, and eliminating the need for tedious and potentially hazardous manual sampling tasks.

Application

The Air Slide Sampler (AS) features a rotating extraction tube equipped with a longitudinal slot, typically 4 mm wide (customisable as required). The tube is mounted within a hollow rotating axle, allowing each extracted increment to fall directly into the sample bottle for efficient collection.

With a small amount of material extracted per rotation, the AS is ideal for continuous or semi-continuous sampling over a defined period, resulting in a reliable and representative composite average sample. The sampling capacity depends on the slot size and tube rotation speed, enabling flexible configuration to match specific process requirements.

Between sampling cycles, the extraction tube is parked with the slot positioned inside a protective guard, placed opposite the material flow. This prevents contamination and wear. The AS is also equipped with an inductive sensor that serves as both a speed monitor and position indicator, ensuring accurate operation and system monitoring.
