Listed here are the Top 10 Compressed Air “Guidelines of Thumb” – designed to answer to the concerns that industrial air compressor consumers talk to about most.
1. CFM delivery per Horse Electric power anticipated at 100 PSIG:
o For “home proprietor” variety of air compressors—2 to 2.5 CFM for every HP
o For Industrial Air-cooled 2-stage air compressors—-3.5 CFM for each HP
o For Compact Vane & Screw air compressors (25 HP or fewer) 4 CFM for every HP
o For large Piston, Screw & Centrifugal air compressors–4.5 to 5 CFM for each HP
Note: THE Additional CFM For every HP – THE Significantly less Energy Utilised.
2. Air Receiver Measurement needed for these varieties of inlet manage:
o Modulating Control————— to 1 gallon for each CFM
o On-Line/Off-Line—————– 3 to 4 gallons for every CFM
o Quit-Begin/ Variable Speed– 4 to 6 gallons per CFM
Observe: THE Much more AIR STORAGE – THE Considerably less Energy Applied
3. Amperage for every Horse Electrical power:
115 Volts——- 1 period——– 10 amps for every horse electric power
230 Volts——- 1 section——– 5 amps for each horse electric power
208 Volts——- 3 period——– 3 amps per horse ability
230 Volts——- 3 stage——– 2.5 amps per horse energy
460 Volts——- 3 phase——– 1.25 amps for each horse energy
574 Volts——- 3 stage——– 1 amp for each horse electrical power
Take note: THE A lot more Strength Economical THE MOTOR – THE Much less Electrical power IS Applied.
4. Air Piping Size by CFM and Tension Fall:
o Compressor Room Header—.25 PSIG tension drop for every 100 toes of piping
o Primary Line—————–.5 PSIG force drop for each 100 feet of piping
o Loop Line—————–1 PSIG tension fall per 100 feet of piping
o Department Line—————2 PSIG strain fall for each 100 ft of piping
Take note: THE Significantly less AIR Stress Fall – THE Less Strength Made use of.
5. Dimensions your Compressed Air Line Filters to be 2 times (2x) your compressor CFM move rate.
o This will decreased your pressure drop 2-3 PSIG and help save an more 1% on electrical electrical power charges.
o Elements will last twice (2x) as lengthy and this can help you save on your maintenance fees.
6. Lowering Air Compressor Pressure options by 2 PSIG will end result in a 1% power discounts.
7. Decreasing Air Compressor Inlet Air Temperature by 10° F will result in a 2% strength discounts.
8. The regular power cost to work an air compressor is close to $.10 for each horse electric power for each hour.
9. Compressed Air procedure leaks totaling the size of a 1/4″ orifice, at 100 PSIG, functioning 24 hrs a working day will squander somewhere around $15,000 really worth of electrical strength a yr.
10. Working with Artificial Compressor Lubricants can conserve you up to 9% of the electricity value of working your compressor as compared to employing a non-artificial lubricant.
COMPRESSED AIR DEFINITIONS:
CFM= Cubic Feet for every Minute – Volumetric air flow price.
Inlet Strain = The precise tension at the inlet flange of the compressor.
PSIG= Kilos Per Sq. Inch Gauge
AMPS=Abbreviation of the plural for Ampere, a device of electrical present-day
Stress = Pressure per device space, calculated in kilos for each square inch (psi).
Stress Dew Stage = For a given force, the temperature at which drinking water will get started to condense out of air.
Inlet Temperature = The whole temperature at the inlet relationship of the compressor.
Realizing these “Procedures of Thumb” can help you in comprehension lots of of the basic principles of compressed air. Implementing these recommendations can support help save you time , strength and income.
