Overview

The Vector VTR-1014 Alpine Air Jet Sieve uses negative-pressure air jet sieving to size fine and ultrafine powders that conventional mechanical shakers cannot reliably classify — from about 10 µm to 4 mm depending on material and sieve stack.

A rotating slit nozzle draws air through the test sieve under controlled vacuum, dispersing agglomerates and passing only particles below the mesh aperture. The result is a reproducible particle size distribution for cement, minerals, chemicals, food ingredients, and pharmaceutical powders where fines control matters.

The VTR-1014 supports workflows aligned with ISO 4610 and DIN 66165, with standard 200 mm test sieves, integrated vacuum, and optional purge accessories for consistent sample conditioning between runs.

Vector VTR-1014 Alpine air jet sieve — negative-pressure fine particle size analyser

Applications

Air jet sieving is the reference method when mechanical vibration cannot break agglomerates or when sub-40 µm fractions must be reported with confidence.

Cement & building materials

Fine fraction and residue on sieve for clinker, cement, limestone, and filler QC — complementing Blaine and strength programmes.

Mining & minerals

Ultrafine tailings, ground ore, and industrial mineral powders where agglomeration skews mechanical sieve results.

Food & agriculture

Flour, starch, sugar, and additive powders — hygienic sieving with repeatable fine-end classification.

Chemicals & pharmaceuticals

Pigments, toners, API, and excipient batches where particle size distribution affects performance and release.

R&D & teaching

Method development and student labs comparing air jet vs mechanical sieving on cohesive fine powders.

Key features

Negative-pressure dispersion, standard sieve compatibility, and accessory support for repeatable fine-particle analysis.

Jet

Air jet dispersion

Rotating nozzle and controlled vacuum break agglomerates so only undersize particles pass — essential for cohesive fines.

10 µm

Ultrafine range

Classify powders from about 10 µm upward — where conventional shakers lose accuracy on fine fractions.

200 mm

Standard test sieves

Uses 200 mm diameter ISO test sieves across a wide mesh range for flexible stack configurations.

Vacuum

Integrated vacuum system

Stable negative pressure for consistent jet velocity and repeatable residue-on-sieve results shift to shift.

Purge

Purge accessories

Optional purge and accessory kit for sample conditioning, cleaning, and line preparation between campaigns.

CE

Laboratory equipment

CE-marked unit for industrial QC labs, commercial testing houses, and research facilities.

How it works

Sample is placed on a test sieve and enclosed under a lid. Vacuum draws air through a rotating slit nozzle, creating a jet that disperses the powder against the mesh. Particles finer than the aperture pass through; the residue is weighed to determine the size fraction.

  • Controlled vacuum — stable jet energy for repeatable dispersion.
  • Timer-based cycles — defined sieving duration per method or internal SOP.
  • Stack flexibility — single-sieve or multi-sieve sequences for distribution curves.

Purge & accessory kit

Consistent results depend on a clean vacuum path and properly conditioned sample. Vector supplies purge and accessory components to support line clearing, sample handling, and routine maintenance between high-throughput shifts.

  • Line preparation — purge accessories for stable vacuum before each run.
  • Sample handling — compatible tooling for cohesive fine powders.
  • Vector support — sieve selection, vacuum sizing, and method guidance.
