  • What compressor do I need?

    When you consider buying a compressor, the offer is wide and can appear quite complex. Here are 10 basic rules to help you finding the compressor that suits your needs.

    1. Determine your type of use: DIY, professional or industrial
      You just occasionally fix small things at home? Or you rather need continuous air flow to keep different applications ruling in your factory?
    2. Define the tools you will work with to define the total Free Air Delivery requirements (FAD). FAD is often expressed in CFM (cubic feet per meter) or l/m (liter per minute)
      Blowing up your mountain bike tires requires much less air flow and pressurethan working with a professional spray gun. To select the right compressor, you need to know the total CFM of all your individual air applications. Add an additional margin of 25% to cover inefficiencies in your network and future growth. FAD is the most important selection criterium.

       

      required CFM = (CFM tool 1+ CFM tool 2 + CFM tool n) + 25% of total CFM

    3. Define your frequency of use: occasional – intermittent – frequent
      Piston compressor technology is suitable for many occasional and intermittent users. Frequent users will benefit from cast iron piston and screw compressor technology.
    4. Define the spacing requirements of your machine: fixed, moveable, remote device and horizontal or vertical vessel
      For easy moving around your compressor, look for comfortable handles and wheels. For remote service, consider an engine driven compressor. Always on the same spot? Go for comfort vibration dampers and a wide stable base. If you have reduced workspace, consider a vertical vessel.
    5. Define the comfort you need in terms of noise level
      With a separate compressor room and an air network, there are less requirements considering the compressor noise level. If you want to position your device close to your working area, silenced compressors are ideal for you.
    6. Define your electrical requirements
      Check if you need a 1 phase or 3 phase compressor. When you have variable flow requirements and more than 5 minutes load, consider a frequency driven compressor. Most of the time, your air consumption will not be constant, so you can gain a lot on energy efficiency.
    7. Define your vessel size
      For an average use of your selected compressor type, the standard proposed vessel size suits the needs, as compressor design is based on years of experience.
    8. Define the accessories you need
      You have delicate air equipment or care extra about the environment, so you need special clean or dry air? Quality Air solutions like dryers and filters exist in many forms, separate or integrated if you require moisture free air.
    9. Check the quality label
      For an optimal return on investment, look for guarantees, like ISO conformity and genuine parts so you can enjoy a long, safe and efficient lifetime of your compressor.
    10. Check ease of maintenance, parts and service availability
      Check serviceability of the device, service intervals and if easy access to genuine parts and services is guaranteed.

    What is compressed air?

  • Which vacuum pump do I need?

    Which vacuum pump do I need? - this is one of the most frequent questions we receive and this is understandable, because there are number of technologies which can provide the same vacuum level and pumping speed. Here is quick and dirty advise how to choose vacuum pump.

      

    Pumping speed of vacuum pump depends on vacuum level. Pump should be sized properly for duty point or duty range - vacuum level at which pump will be operating (not to be confused with nominal pumping speed referred to point at which pump actually never works). Important to remember that not every pump type can run continuously in the complete range.

    Oil sealed vane pumps can overheat and “smoke” above 400 mbar. Choose dry vane, claw or liquid ring pump instead.
    Setting exact required vacuum level helps to reduce energy consumption. This is possible with Quincy QSV and QCV vacuum pumps.


    Time to reach required vacuum level is important in cyclic processes, for example for emptying vacuum chamber in food packaging. The shorter pump-down time – the faster cycle - the faster production. Pumping speed should be calculated from atmospheric pressure to duty point and pump should be able to handle complete range.

    Demand for vacuum can change over time in a production process. This is typical for example for holding applications with CNC wood routers. QCV or QSV vacuum pump with variable speed drive can reduce energy consumption. Centralized systems where one pump with variable speed drive replaces multiple smaller pumps is an efficient way to distribute lead.

    Sucked air goes through the vacuum pump. High temperature air, contamination, solvent vapor can come into contact with oil and damage the pump. If air contains vapors that can damage oil, opt for dry vacuum pump. It will help you to reduce maintenance cost. Also they are the best for handling saturated vapors. In this case pumping speed can increase by 15%.

    High air temperature can decrease viscosity of the oil and lead to overheating.
    Liquid ring pumps can handle particles without risk of damage, but their performance depends on water temperature and can greately decrease in hot environment.
