Atlas® AF9 Plus 7.5HP 120 Gal Compressor #ATEATAF9PLUS-17-120G-H

Atlas AF9 Plus — 7.5HP 120 Gallon Compressor (Earlier Generation)

A two-bay shop that needs 120-gallon tank reserve on a strict budget has two ways to get it: pay current-generation pricing, or buy the earlier-generation unit that already proved itself in the field. The Atlas AF9 Plus (AF9/17, 120-gallon horizontal) is that second path: 7.5 horsepower at 1725 RPM on 230VAC single-phase, delivering 24.8 CFM at 100 PSI into a tank 33% bigger than the 80-gallon class — same Plus Package protections, previous-generation price.

One honest note up front: this is the earlier generation of the 7.5HP line — the current model (MPAF9P-120H, also in stock) has live product-page specs and a published warranty. This page's specs come from the manufacturer's catalog documentation, and its model-specific warranty isn't published — confirm coverage at purchase.

Who the Atlas AF9 Plus Is Built For

• Two-bay shops buying on value — the earlier-generation 7.5HP line delivers the same tank class and Plus Package (low-oil shut-off, aftercooler, auto tank drain) at previous-generation pricing.
• Shops on 230VAC single-phase service (60Hz) — standard single-phase shop power on a 40-amp-class circuit.
• Buyers who want the big tank specifically — 120 gallons carries 33% more storage than the 80-gallon class, smoothing tool demand between pump cycles.
• Shops with height or layout constraints — the horizontal configuration also allows location in an overhead storage area per the manufacturer's catalog.
• Buyers comfortable with catalog-documented specs — the specs here are manufacturer-published (catalog documentation), but there is no live product page for this generation; we present it honestly.

What the Atlas AF9 Plus Is NOT Built For

This is not the current-generation 7.5HP — if you want the live-spec, published-warranty machine, the MPAF9P-120H is that unit (we stock both). It's also not for shops needing the 10HP class, and its CFM ratings use a different pressure basis than the current line, so don't compare them head-to-head without calling us.

Important sizing note: confirm 230VAC single-phase service, measure the floor for a horizontal 120-gallon tank, and note the rating basis (24.8 CFM @ 100 PSI) differs from the current line's basis before purchase. Questions on fit? Call (817) 865-3707 before ordering — we confirm compatibility, not guesses.

What Makes the Atlas AF9 Plus Different

7.5HP on single-phase power

24.8 CFM delivered at 100 PSI (22.8 at 175) from a 7.5 HP motor at 1725 RPM, on 230VAC 1-phase 60Hz.

• 7.5 HP @ 1725 RPM
• 24.8 CFM @ 100 PSI
• 145–175 PSI range

Plus Package protections

Automatic low-oil shut-off, aftercooler, and automatic tank drain — the same protection kit as the current line, fitted from the factory.

The 120-gallon advantage

33% more stored air than the 80-gallon class — tools keep working through demand spikes, the pump cycles less, and the horizontal configuration opens placement options (including overhead).

Best For

• Value-driven two-bay shops
• 120-gal tank class
• 1-phase service
• Plus Package standard

Not Ideal For

• Buyers wanting current-gen specs/warranty (see MPAF9P-120H)
• 10HP-class demand
• 3-phase shops

AF9 Plus vs the current-generation MPAF9P-120H

Same tank, same protections, two generations — we stock both and will tell you honestly which fits the budget and the shop.
