The HMK-200 Intelligent Air Jet Sieve builds upon the capabilities of the standard AIR-200, while retaining the same hardware. It uses air jets to analyze the particle size distribution and size limits of powders, while effectively separating and filtering them.
It comprises a nozzle, undersieve sample collector, standard test sieves, sieve plate, sieving control and analysis system, transparent cover, vacuum cleaner, among other components. Similar to the standard model, HMK-200 offers efficient sieving with a short processing time, minimizes sieve clogging, and effectively eliminates agglomeration and static electricity. It can sieve particles of up to 3 μm. The equipment also features an additional sieve-opening facility, where the nozzle continuously sweeps the sieve holes to further minimize the risk of clogging.
Beyond the standard model's automatic calculation of oversize percentages, the HMK-200 also calculates interval and undersize percentages. The sieving results can be printed and compared with the standard for storage.
The equipment has export functionality and optional unlimited data storage. It is also tailored to over 200 pharmaceutically relevant standard operating procedures. The system complies with ASTM D5158, ISO 4610, the United States Pharmacopeia (USP), and the European Pharmacopoeia (EP) standards.

It uses an electronic vortex generator that creates a negative-pressure air vortex via a vacuum. This moves the powder through the nozzle, where it collides with the transparent cover. The vortex then reabsorbs the powder, along with the removed agglomerates, into the standard test sieve based on particle size. Larger particles stay on top, while smaller particles move through the sieve and get collected in the sample collector.
The residue on the collection sieve is weighed, and the details are entered into the software, which automatically calculates the percentage of powder retained and prints the results via a built-in thermal printer.
