Right here are the Best Ten Compressed Air « Policies of Thumb » – created to react to the questions that industrial air compressor consumers check with about most.
1. CFM shipping for every Horse Electricity expected at 100 PSIG:
o For « household proprietor » type of air compressors—2 to 2.5 CFM for each HP
o For Industrial Air-cooled 2-stage air compressors—-3.5 CFM per HP
o For Smaller Vane & Screw air compressors (25 HP or much less) 4 CFM for every HP
o For huge Piston, Screw & Centrifugal air compressors–4.5 to 5 CFM for every HP
Note: THE Additional CFM Per HP – THE Much less Energy Applied.
2. Air Receiver Dimensions desired for these forms of inlet control:
o Modulating Regulate————— to 1 gallon for every CFM
o On-Line/Off-Line—————– 3 to 4 gallons for each CFM
o Cease-Begin/ Variable Velocity– 4 to 6 gallons per CFM
Notice: THE Much more AIR STORAGE – THE Significantly less Vitality Applied
3. Amperage for each Horse Ability:
115 Volts——- 1 section——– 10 amps for every horse electricity
230 Volts——- 1 phase——– 5 amps for each horse power
208 Volts——- 3 phase——– 3 amps per horse electricity
230 Volts——- 3 stage——– 2.5 amps per horse electrical power
460 Volts——- 3 period——– 1.25 amps for each horse electricity
574 Volts——- 3 phase——– 1 amp per horse energy
Notice: THE Far more Power Economical THE MOTOR – THE Considerably less Vitality IS Utilised.
4. Air Piping Dimension by CFM and Force Drop:
o Compressor Room Header—.25 PSIG force drop per 100 feet of piping
o Main Line—————–.5 PSIG force drop for each 100 ft of piping
o Loop Line—————–1 PSIG strain drop for every 100 feet of piping
o Branch Line—————2 PSIG strain drop for every 100 feet of piping
Observe: THE Considerably less AIR Strain Fall – THE Less Power Utilized.
5. Sizing your Compressed Air Line Filters to be two times (2x) your compressor CFM stream rate.
o This will reduced your strain fall 2-3 PSIG and save an more 1% on electrical power prices.
o Factors will past twice (2x) as extensive and this can conserve on your maintenance fees.
6. Decreasing Air Compressor Stress settings by 2 PSIG will consequence in a 1% electricity personal savings.
7. Decreasing Air Compressor Inlet Air Temperature by 10° F will consequence in a 2% electrical power savings.
8. The normal strength value to run an air compressor is roughly $.10 for every horse electric power for every hour.
9. Compressed Air procedure leaks totaling the sizing of a 1/4″ orifice, at 100 PSIG, functioning 24 hours a day will squander around $15,000 worthy of of electrical power a year.
10. Working with Synthetic Compressor Lubricants can save you up to 9% of the strength value of working your compressor as when compared to working with a non-synthetic lubricant.
COMPRESSED AIR DEFINITIONS:
CFM= Cubic Feet per Minute – Volumetric air stream price.
Inlet Strain = The actual force at the inlet flange of the compressor.
PSIG= Pounds For each Square Inch Gauge
AMPS=Abbreviation of the plural for Ampere, a unit of electrical latest
Pressure = Force for each device location, measured in kilos for each square inch (psi).
Strain Dew Issue = For a given strain, the temperature at which drinking water will start to condense out of air.
Inlet Temperature = The total temperature at the inlet link of the compressor.
Knowing these « Guidelines of Thumb » can support you in knowing several of the basics of compressed air. Making use of these recommendations can enable conserve you time , power and income.
