How To Calculate Cfm Air Compressor To Choose Correct Inline Filter

Air compressors for home and occasional DIY.

A t SGS, there is a huge range of direct drive and belt drive air compressors. Nosotros empathize that it tin seem daunting to try and pair your air tools with a specific air compressor. Especially every bit the range of choices bachelor is then wide. Air compressors tin can be used for all manner of work on vehicles and home. For example, touching upward the paint work, wrenching off wheel nuts, cut metalwork etc. How do you know which one you should use? The best air compressor isn't ever the right air compressor for the job. We've put together a simple user guide and cheque list to help you narrow the field and make up one's mind which compressor is worth your investment.

Quick Start Guide

1. What will y'all be using the compressor for?

Having an understanding what you volition be using your air compressor for is the nearly important factor when looking to buy a compressor. All compressors come with specific warranties to cover infrequent apply for DIY jobs or frequent . Make certain yous cull the correct compressor for your application. If you lot have a specific job in mind then check out our compressor kits with everything yous need to become started.

2. CFM requirement

CFM requirement - the single biggest consideration when buying a compressor. Knowing what CFM your air compressor needs to produce in club to ability all of your air tools. Find the SCFM requirement of your tool from it'south manual or technical specification.

Case: if y'all desire to run a spray gun (6 SCFM):

6 SCFM x 1.2 = at least a 7.ii CFM compressor

3. Choosing a tank size

With tank sizes ranging from vi litres to 500 litres+, choosing the perfect capacity air tank / receiver will seriously bear on the performance of your compressor. To detect the minimum tank size of the compressor you need multiple your tool's required SCFM by 6.

For example, if you run an touch wrench (8 SCFM):
8 SCFM 10 6 = at least a 48 litre compressor tank

4. Oil-less or oil compressor

Oil-less compressors are low maintenance and gratis from contaminants. A standard oiled generally compressor will produce a larger output and run quieter

i. Direct Drive or Chugalug Drive?

We split our range of compressors into ii specific ranges - straight bulldoze and belt drive - each with it'southward ain specific warranty tailored for its intended use. If y'all're a DIY user, hobbyist or occasional user of an air compressor, we'd suggest one of these SGS compressors.

2. Agreement Required CFM

One of the nigh important consideration when purchasing a new air compressor is the air menstruum the compressor can deliver. Air tools take certain requirements to run at optimum capacity. More of import is the Required SCFM or Standard Cubic Feet per Minute.

All air tools will have a required SCFM, merely in general smaller air tools require between 0-5 SCFM. While larger tools can need 10 or more than SCFM.

CFM stands for Cubic Feet per Minute and is the volume of air the compressor tin can pump out per minute.

The beginning thing you need to work out is how much air will y'all need to ability your tool. To work this out we need to know how much air menstruation the compressor produces and how much your tool requires to run. Most air tools will have specific requirements for air volume and pressure. Your compressor must run across these requirements for the tool to part the all-time they can.

Working out your CFM requirement

Find the required air flow (SCFM)
of your air tools. This information will exist in your tools user guide or manufacturers website.
If you lot're going to be running multiple tools you lot'll need to add together together the individualSCFM of each tool. Most DIY compressors are designed to run only one tool at a time. You can successfully run several tools simultaneously on larger more commercial compressors.
To find the minimum required CFM of the compressor you need multiply your tool's required SCFM by 1.two

Example: if you want to run a spray gun (half dozen SCFM):

6 SCFM x 1.2 = at least a 7.2 CFM compressor

This is a rough guide just. Larger compressors with higher CFM and bigger tanks will always requite you improve performing tools. You may adopt buying the largest compressor within your budget.

Typical SCFM Requirements

These are some typical values for various air tools. You lot should always check the exact requirement of your tool by consulting its user guide.

Tool Blazon	Req SCFM's	Tool Blazon	Req. SCFM's	Tool Type	Req. SCFM's
Angle Disc Grinder	6 SCFM	Dual Action Sander	6 SCFM	Ratchet ane/four"	3 SCFM
Air Drill 1/2	4 SCFM	Grease/caulking gun	four SCFM	Ratchet iii/8"	4 SCFM
Air Drill 3/8	4 SCFM	High Speed Grinder v"	4 SCFM	Sand Blaster	4 SCFM
Butterfly Impact	3 SCFM	Imapct Wrench one/2"	5 SCFM	Spray Gun	6-xviii SCFM
Air Hammer	4 SCFM	Impact Wrench 3/4"	seven SCFM	Straight Line Sander	7 SCFM
Cut Off Tool	4 SCFM	Nailer	i SCFM
Die Grinder	8 SCFM	Orbital Jitterbug Sander	half-dozen SCFM

CFM vs FAD

CFM (FAD) is generally third less than CFM (Displacement), if your air compressor is advertised as 10 CFM (deportation), the Gratuitous Air Delivery (FAD) is probably around 6.6 CFM.

FAD is "gratis air delivery" and is the volume of air actually discharged. Compressors are always listed with the theoretical displacement, not the actual amount of air delivered. FAD is far more useful the CFM as you can come across the actual "power" a compressor has available for tools etc.

TOP TIP: Air flow is lost through air hoses, hose fittings, filters, lubricators, and especially through quick-connect couplings. If you practice program to run your air tool some distance abroad from the bodily compressor or with any of these peripherals, you will need to consider this pressure drop when choosing your compressor. The more CFM your compressor produces, the better your tool will run, fifty-fifty with longer hoses and more fittings.

Peak TIP: Never use extension leads with an air compressors! The voltage drop from an extension cable tin damage the air compressor motor. Instead use a longer air hose.

Working Pressure

The pressure generated inside the tank of an air compressor is measured in Bar and Pounds Per Foursquare Inch – or PSI. Most compressors accept a working pressure of 8 bar / 115 PSI which is more than sufficient for DIY and hobby air tools (normally around xc PSI)

Some of the more powerful air compressors nosotros sell in our commercial range accept college working pressures (145 PSI+). Again, y'all can always check to see what working pressure is required for your air tool by looking at the user manual or contacting the manufacturer.

Working out your required tank size

different air compressor sizes — As a dominion, the larger the air tank your compressor has the better and longer your tool will run at a more consistent CFM. Considering a larger air tank will exist depleted less frequently than a smaller tank, it's worth investing in a large plenty tank to complete the job you lot accept in mind – for example, even though a spray gun will piece of work with a small six litre compressor, it will only piece of work in very short bursts. 6 litres would be enough for spraying the body of a guitar, notwithstanding if you want to paint a whole car or van, yous'd probably want at least a 100 litre air compressor.

To find the minimum tank size of the compressor you need to multiply your tool's required SCFM by six.

For example, if you lot run an impact wrench (8 SCFM):
eight SCFM x half dozen = at least a 48 litre compressor tank

Again, this is a rough guide and the larger tank your compressor has, the ameliorate the performance of your tool. Below is a table of our range of compressors to help you cull the right one for your applications.

Standard vs. Oil-less Air Compressors

Oil-less compressors accept go increasingly more popular for at home and lite DIY use. This table should help to sympathise the pros and cons of an oil-free compressor vs a standard oiled compressor then you can brand an informed ownership decision.

	Oiled Air Compressors	Oil-less Air Compressors
Lubrication	Standard air compressors use a lubricating oil to effectively and reliably to go along the pistons moving in a good working order.	In oil-less compressors the pistons are permanently pre-lubricated in a fabric such as Teflon.
Maintenance	The oil will need changing periodically. Neglecting maintenance will cause irreversible damage and invalidate your warranty.	No oil means no oil changes, pregnant minimal maintenance requirements.
Weight	Standard compressors weigh considerably more than oil-free compressors as a rule.	Oil-less compressors crave less parts, therefore they tend to be lighter the alternatives.
Usage	Standard compressors are durable and hard-wearing. Most industrial and commercial air compressors will apply oil.	Teflon coated cylinders will get worn down over time, pregnant your piston volition showtime to get dry and performance will suffer. .
Noise	Standard compressors tend to be a lot quieter than oil-less alternatives, purely because they're liquid lubricated.
Contaminates	Having an oiled compressor means a adventure of getting contaminates in your air line. If yous're using a spray gun, it may ruin your work.	No oil means no contaminates, making these compressors popular with spray painters and clinical settings.

When you commencement looking at the more than professional air compressors you'll start seeing a larger variety of power options. You might desire a 400V, three-phase power supply for a commercial setting, or a petrol/diesel compressor for more flexibility.
