Scroll Air Compressors

How many CFM do the scroll compressors deliver?

The Anest Iwata SLE-5 lists 5 HP and 14.8 CFM; the SLE-10 lists 10 HP and 29.6 CFM. The SLE-20 lists 20 HP and 59.2 CFM.

Those are model-specific figures, not a CFM-per-horsepower formula. The full collection has 34 active listings: 32 Anest Iwata and 2 Schulz. Anest Iwata entries list 115 PSI maximum pressure, with SLE airflow spanning 2.7 CFM on the SLE-1 to 172.5 CFM on the SLE-60.

CFM is as listed by the manufacturer; the maximum pressure column does not establish the airflow test pressure, so use the model's rating basis for sizing. List the equipment that runs together and the air it consumes at working pressure to build your shortlist.

Which scroll units include a receiver?

The Anest Iwata SLT-2 lists a 30 gallon receiver and 5.4 CFM, while the SLT-5 lists a 60 gallon receiver and 14.8 CFM. The SLT-7.5 lists an 80 gallon receiver and 22.6 CFM.

The SLT-10 also lists an 80 gallon receiver, at 29.7 CFM. Duplex SLT-10D, SLT-15D and SLT-20D models list 120 gallon horizontal receivers and 29.6 CFM, 45.2 CFM and 59.4 CFM respectively. Their enclosed SLTE counterparts list the same airflow figures and receiver capacities.

Schulz SCR 4010 TS lists 10 HP, 28.5 CFM and a 120 gallon integrated receiver. Its pressure entry is 87–116 PSI (6–8 bar). A receiver typically helps buffer short demand peaks, while sustained demand still needs enough compressor output.

What does the base-mount scroll range cover?

The Anest Iwata SLE base-mount range covers 1 to 60 HP, with 2.7 CFM on SLE-1 and 172.5 CFM on SLE-60. The table contains 18 base-mount or no-receiver-listed entries in total.

The SLE-15 lists 44.4 CFM, SLE-30 lists 88.8 CFM and SLE-40 lists 118.4 CFM. SLB-10 lists 29.7 CFM, while SLE-10 lists 29.6 CFM, so keeping the series name with the horsepower helps distinguish similar-looking choices.

The table also includes the enclosed SLBE at 2 HP and 5.4 CFM. Some rows are grouped here because a receiver is not listed; confirm the exact package contents rather than treating a blank specification as proof of what is excluded.

How quiet are scroll compressors?

Listed Anest Iwata SLE sound figures span 46–63 dB(A); tank-mounted SLT figures span 51–79 dB(A). Enclosed SLTE tank models span 50–69 dB(A).

The SLE-1 and SLE-2 each list 46 dB(A). For tank-mounted examples, SLT-5 lists 68 dB(A) and SLTE-5 lists 61 dB(A), with both listing 5 HP and 14.8 CFM. The enclosed duplex SLTE-10D lists 62 dB(A), alongside 10 HP and 29.6 CFM.

Both Schulz scroll entries list 69 dB(A). These are the manufacturer's listed figures, and measurement conditions need to match for a direct noise comparison. Use the sound column with the airflow and configuration you need, rather than choosing an enclosure on its name alone.

Common questions

How many CFM does a 5 HP scroll compressor deliver?

Anest Iwata SLB-5, SLE-5, SLT-5 and SLTE-5 each list 14.8 CFM. Schulz SCR 4005 lists 12.5 CFM.

What is the listed maximum pressure for Anest Iwata scroll units?

The Anest Iwata models in these tables list 115 PSI maximum pressure.

What size tank comes with a duplex scroll?

The listed Anest Iwata SLT and SLTE duplex models have 120 gallon horizontal receivers. The 15 HP versions list 45.2 CFM.

Does oil-free compression establish my air-purity class?

Scroll units are oil-free in the compression chamber; confirm the air-purity class your application needs against the manufacturer's documentation for the complete system.
