Airflow Screening Machine XN-QWA-200

Name: Airflow Screening Machine XN-QWA-200
Equipment Type: Air Jet Sieve for Analytical Fine-Particle Screening
Product Code: XN-QWA-200
Brand: Xnergy

Product Introduction:

The XN-QWA-200 Airflow Screening Machine — also known as an air jet sieve — uses aerodynamic (air-jet) screening to keep samples well dispersed and prevent agglomeration, making it ideal for the screening analysis of low-density, easily agglomerating fine particles. It suits analytical sieves with a mesh aperture of 10 μm and above, handles samples up to 100 g, and completes a typical screening in 2–3 minutes. A specially non-metallized screen avoids metal contamination, while the adjustable nozzle speed gives flexible, gentle screening. The unit runs with a manually adjustable industrial pump, or an optional automatic pump, and its continuous airflow ensures a reproducible screening process and repeatable results.

Key Features:

Aerodynamic air-jet screening keeps particles dispersed and prevents agglomeration
Suited to low-density, easily agglomerating fine powders from 10 μm to 100 μm
Specially non-metallized screen to avoid metal contamination
Adjustable nozzle speed (5–55 r/min) for flexible, repeatable screening
Typical screening time of 2–3 minutes
Programmable timer (0–99 min) with 9 storable parameter combinations plus quick start
Runs with a manually adjustable industrial pump or an optional automatic pump
Continuous airflow for a reproducible process and repeatable results

Technical Specifications:

The XN-QWA-200 is supplied for a single-tier (Level 1) screen stack; a Level 2 stack requires a cyclone collector. The screening pump (manual industrial or optional automatic) and accessories are specified at order time.

Application Areas:

Screening analysis of low-density, easily agglomerating fine powders
Particle-size and fines analysis for materials from 10 μm to 100 μm
Quality control where a non-metallized, contamination-free screen is required
Reproducible, repeatable screening for method development and routine testing
Fine-powder fractions that blind or bridge on a conventional vibrating sieve
Battery R&D — screening fine cathode, anode, and additive powders

Maintenance:

Clean the screen, nozzle, and chamber with a soft brush or compressed air after each use
Handle the non-metallized screen carefully and inspect it for damage before each run
If the equipment is not used for an extended period, clean and store the unit in a dry place
Periodically check the pump, hoses, and air connections for leaks or blockages
Inspect the screen mesh regularly and replace to maintain screening accuracy

Safety Notes:

Keep hands clear of the moving nozzle assembly and screen during operation
The unit should be operated by a single trained operator
Disassembly and internal servicing should be performed only by qualified technicians
Verify the pump connection and stable placement before operation

Specifications are provided for reference and may be adjusted to suit specific process requirements. Screen aperture, pump type, and accessory configuration are specified at order time.

Note: Specifications listed above are typical and for reference only. Actual screening performance depends on the powder, mesh aperture, load, and airflow setting. The XN-QWA-200 is a single-sieve air-jet analyzer purpose-built for fine, low-density, and easily agglomerating powders (10–100 μm) that blind or bridge on a vibrating screen — the air jet keeps particles dispersed for a clean cut. Where you instead need to split a sample into several fractions at once across a broad 5–1000 mesh range, the vibrating XN-ZDS Sieve Shaker is the multi-layer alternative. The fine powders analyzed here are typically produced upstream on the XN-MS Nano Sand Mill for wet nano-grinding or the XN-YXQM Planetary Ball Mill for fine grinding.
