The Mikro Air Jet Sieve™ made in the USA is an accurate and reliable single-sieve system for 10 to 100g samples of dry powders from 4.75mm to 20μm (No. 4 to No. 635). A rotating slotted nozzle supplies positive air pressure to gently fluidize the sample in a covered test sieve. Exiting air is drawn downward with an external vacuum system, creating a negative pressure to carry undersize particles to a collection canister. Air Jet sieving action is gentle, effective, and especially useful for fragile or low specific gravity materials. Operation is clean and quiet, and takes up minimal space. Test times and vacuum/pressure settings are controlled through the integrated computer, with touch screen controls and display. The controller has memory for up to nine preset test times to ensure easy operation and test-to-test repeatability. Basic or Advanced versions are offered, each with separate models configured for use with ISO 200mm and older style Air Jet Test Sieves, or with ASTM 8in diameter Test Sieves. Inquire for parts to adapt 200mm or 8in models to use alternate sieve sizes. The SSA-9 Low Profile O-Ring is required for all sieves and replaces the original sealing gasket from original Air Jet Test Sieves. For small samples, inquire for special 83mm diameter sieves and adapter plate to allow sieving of three samples at once. Each model is 16.5x10.5x7.5in (419x267x191mm) WxDxH, and operates at 90-240V/50-60Hz.
Basic Mikro Air Jet Sieve™ consists of the base unit with a clear acrylic sieve cover, slotted brass air nozzle, electronic controls and integrated computer and touch screen display. The 15-Watt bevel-gear motor has lifetime lubricated bearings. The cast aluminum instrument housing features a built-in pressure differential gauge and has an attractive baked enamel finish. An integral electrical outlet provides a convenient connection for the vacuum system, which is purchased separately. Vacuum is monitored at the housing outlet and has a control valve for adjustment.
AJ-103 accepts 200mm ISO Test Sieves or old-style Air Jet Test Sieves.
AJ-103B model is configured for ASTM E11 8in (203mm) diameter Test Sieves.
Advanced Mikro Air Jet Sieve™ consists of the Basic Siever with Windows-compatible software to interface with an electronic balance. This system automatically collects and transfers sieve and fraction weights to the user’s computer for networking and printing functions. Test results can be reported in a variety of graphs and tabular formats, and saved directly to the computer. A serial interface cable is included. This model can be ordered directly or by purchasing a simple AJA-111 upgrade to unlock these features on an existing Basic unit.
AJ-105 accepts 200mm ISO Test Sieves or old-style Air Jet Test Sieves.
AJ-105B model is configured for ASTM E11 8in (203mm) diameter Test Sieves.
AJ-105 models or upgrades require an AJA-135 Electronic Balance, purchased separately. The Balance has a capacity of 4,200g with a readability of 0.01g, and is supplied with an interface cable.
A vacuum system is required for operation and purchased separately. The AJA-134 Vacuum System is recommended for best performance over a wide range of materials, including very fine and conductive specimens. AJA-133 Standard Vacuum System has a low-noise 1,000-Watt motor and low-profile epoxy-lined steel filter canister with 4gal (15L) capacity. Note that the Standard Vacuum System is not designed for conductive materials or materials with high fines content. The AJA-4 Cyclone Collector, used in conjunction with the vacuum systems, assures greatest recovery of sub-micron fines.
