  • Page 5: Introduction

    Introduction Meech Blowers are powerful static eliminators which will give many years of excellent service, provided that the following instructions are observed closely.
  • Page 6 ELECTRICAL SUPPLY. The Power Unit converts the primary electricity supply into a high voltage, low amperage output. This energy is transferred to the Meech Bars in the mouth of the blower by the HT cable. The titanium pins of the bars emit the energy to form an ionised air corona. The fans inside the blower provide an air flow to transport the corona to the object to be neutralised.

  • Page 7: Installation

    Installation The correct positioning of the blower is vital to the efficient operation. Please observe the following instructions. Distance From Object Although the blower has excellent long range neutralisation capabilities, the general rule is that it should be as close to the object as possible. If we say neutralisation power at a distance from the object of 30cm is 100% then the relative n eutralisation performance at longer distances.
  • Page 8 It is recommended that the following procedure be observed for safe Caution operation of the Model 935 Blower: It is recommended that the following procedure be observed for safe operation of The supply voltage of the power supply must be interlocked with the ON/OFF the Model 935 Blower: control of the machine to which the equipment is fitted.

  • Page 9: Maintenance

    Maintenance The Static Eliminator bars in the mouth of the blower should be cleaned regularly to keep the emitter pins free from dust and other contaminants. A toothbrush is ideal for this. Cleaning of the emitter pins of the ionisation bars Ensure the blower is switched off and isolated from the mains electrical supply.
  • Page 10 Using a tooth brush (or a similar brush with non conductive bristles), brush the pins and upper surface of the two white ionising bars. With a cloth clean the exterior and interior surfaces of the blower.
  • Page 11 Replace the black plastic grill by the reverse procedure.

  • Page 12: Ce Approval

    CE Approval An EC declaration of conformity for this product exists in respect of the Low Voltage Directive: 72/23/EEC (“LVD”) & Electromagnetic Compatibility Directive: 89/336/EEC (“EMCD”)

  • Page 13: Fault Finding

    High voltage electrical equipment should not make contact with water. The Model 935 blower forms part of a system, comprising itself and a Model 903 or 904 power supply. To verify where a fault may have occurred it is important to test each item of the system individually.
  • Page 14 Using a high voltage probe (RS 610 281) and meter (RS 610 590) measure the voltage on the pins of the ionising bars. The voltage should be approximately ~ 6.5 kV. If the voltage is below 4.5 kV, then the item should be returned to Meech for service and / or repair.
  • Page 15 Connect one end of the cable to the earth post of the blower. Approach the pin of the bar with the other end of the cable. As the conductors of the cable approaches the pins of the bar a small faint spark should jump from the pin to the cable conductors.

  • Page 16: Repairs And Warranty

    Repairs And Warranty The 935 blower is warranted by Meech Static Eliminators Ltd to the original purchaser against defects in material and workmanship for one year after purchase. Should any malfunction occur, please return the bar directly to Meech Static Eliminators or your local agent.
