SIEVING MACHINE MODEL:

Air Sizer 200

General Information

The Air Sizer 200 has an air nozzle, which is set rotating. The sieve with a Plexiglas lid is put on top of that. A

vacuum unit generates a jet of air, which disperses the particles through the air nozzle on the sieve.

The material, which is smaller than the mesh size of the air jet sieve, is transported by the backflow of the air

into the filter unit or directly into the vacuum cleaner. The jet of air de-agglomerates the particles and cleans the

sieve mesh constantly.

The Air Sizer 200 is specially designed for the dry sieving and the particle size determination of fine-grained,

dry, pourable and dispersed bulk materials. The sieve holder is suitable for 8“(203 mm) diameter test sieves

(premium air jet sieves)

Advantages

xCompact and portable (weighing only 14 kg)

xRequires only small storage space due to small footprint

xThe device is essentially maintenance free if cleaned regularly

xEasy to use

xIdeal for electrostatic materials

xWide range voltage supply

xCan reduce the average sieving times in samples with a high fine fraction

xVariable vacuum control

The Air Sizer 200 is not recommended for any wet sieving operations!

1. Setting up

Setting Up

Electrical connections

xEnsure that the voltage and frequency on the rating label, at the rear of the Air Sizer 200

correspond with the local electrical mains supply.

xConnect the Air Sizer 200 to the power supply using the connection cable provided.

Do not connect to any other supply other than stated on the rating label,

otherwise electrical and mechanical components can be damaged.

Ambient temperature: 5°C to 40°C

If the ambient temperature is exceeded or drops below the specified value

the electrical and mechanical components may become damaged and the

performance data can change to an unknown degree.

Atmospheric humidity:

Maximum relative humidity 80% at temperatures up to 31°C,

with linear reduction down to 50% relative humidity at 40°C.

At high atmospheric humidity the electrical and mechanical components

may become damaged and the performance data can change to an

unknown degree.

xMains power connection

Mains power connection with integral line filter. Ensure the IEC connector

on the mains lead is pushed fully into the mains inlet at the rear of the machine.

xMains Connection Indication

If the power of the Air sizer 200 is switched “ON”, the display LED lights up.

xProcess Timer

The process timer is a digital 00:10-99:50 minute timer. Operating periods

are increased by pressing the “ޔ” button and decreased by pressing the “ޕ“ button.

1. Technical specifications

Start-up and commissioning

The machine should be set up according to the following procedure.

The following items should be removed from the carton and checked before the Air Sizer 200 is

operated (Take Care the Air sizer 200 weighs 14 kg):

x1 off Set-up Instructions.

x1 off Mains Cable.

x1 off Air Sizer fitted

x1 off Plexiglas lid

xSoft-Faced Mallet

xTest Sieving Manual.

Position the Air Sizer 200 on a level, rigid and robust bench, suitable for the operation of the Air

Sizer. Being placed on a level surface ensures symmetrical distribution of the sample over the sieve,

during operation.

1. Setting up

Operating Instructions

Switching On and Off

xPress the on/off switch at the back to turn on the device.

When the switch is in the "off" position, the device must be disconnected completely from the mains

power supply (f.e. before cleaning the device).

Inserting the test sieve

The Air Sizer 200 is intended for test sieves with a diameter of 203mm (8 inches). The range of mesh

fineness extends from 10μm to approx. 4mm.

xPlace the sieve in the nozzle compartment.

xFit the Plexiglas lid provided.

NOTE:

The Air Sizer 200 cannot be started until the sieve has been inserted and the lid put on.

Soft-faced mallet – Application and Use

Any caking that has built up during the sieving process is knocked off the inside of the lid by means

of the soft-faced mallet.

Tap lightly, striking the centre of the knob as far as possible.

1. Technical specifications

Use of the machine for the intended purpose

Risk of explosion or fire

xOn account of its design, the device is not suitable for use in hazardous

(potentially explosive) atmospheres.

xDo not operate the device in a hazardous atmosphere.

Risk of explosion or fire

Changing sample characteristics

xNote that the characteristics and accordingly the danger presented by a sample

can change during sieving.

xDo not sieve any potentially explosive or combustible materials in this device.

Danger of personal injury

Dangerous nature of the sample

xDepending on the dangerous nature of your sample, take the necessary

measures to rule out any danger to persons.

xObserve the safety guidelines and datasheets of your sample material.

Note: Area of use of the machine

xThis machine is a laboratory machine designed for 8-hour single-shift operation.

xThis machine may not be used as a production machine nor is it intended for

continuous operation.

Note: Defects in components due to liquids

Penetration of liquids inside the housing

xComponents are damaged and the correct functioning of the device is no longer

assured.

xDo not use this device for any wet sieving.

Hearing damage or hearing loss

Suction noise at the suction opening

xThe volume and/or force of drawn-in air can damage hearing or cause hearing

loss.

xKeep your ears away from the air inlet in the channel. Use hearing protection.

Failure to hear acoustic signals

Loud suction noise on the air inlet

xIt is possible that some acoustic warnings and voice communication may not be

noticed.

xTake the strength of the suction noise into consideration when designing your

acoustic signals in the working environment. Possibly additionally use visual

signals.

Noise characteristics:

The Air Sizer 200 itself is constructed in a manner that prevents any significant development of noise. The noise

characteristics of the connected industrial vacuum cleaner depend on the set suction force and suction load.

QAQC LAB 589 Rappahannock Drive White Stone Va 22578 TEL (804) 318-3686

1. Setting up

Note: Ensure that the differential pressure or vacuum generated by your vacuum cleaner or

the suction is not greater than 99 mbar.

The maximum quantity of material to be sieved depends on the mesh size and sieve

size.

Rated Power: Air Sizer 200 : maximum 50 watts

Air Sizer 200 + vacuum cleaner: maximum 1450 watts

When connecting the power cable to the mains supply, use an external fuse that

complies with the regulations applicable to the place of installation .

xPlease check the rating label for details on the necessary voltage and frequency

for the device.

xMake sure the levels agree with the existing mains power supply.

xUse the supplied connection cable to connect the device to the mains power

supply.

The external fuse must be at least T15A (230V) T15A (100/120V).

Danger to life through electric shock

xAn electric shock can lead to burns and to cardiac arrhythmias or to respiratory

arrest and cardiac arrest.

xThe device may only be operated with plugs that have a protective conductor

(earthed).

Connecting the external Industrial Vacuum cleaner

Electric shock

Faulty power cable

xWhen you switch the device on there is danger of an electrical shock if the power

cable for the external suction device is damaged.

xBefore use, check the power cable between the sieve device and the suction

device for possible damage.

xNever use a damaged power cable!

Objects thrown-out or falling down

Connection of compressed air instead of vacuum cleaner

xIf compressed air is connected to one of the two air openings, the sieve lid and

the sieve will be hurled out.

xThis device may not be operated with compressed air.

The Air Sizer 200 can be operated only with a suction extractor, such as for example a vacuum

cleaner.
