On a 7.5 HP machine it is the whole point. This is the compact end of the enclosed Schulz range: 500 lbs, a footprint of 49.4\" by 23.6\", and 53.5\" of height — proportions that take a slot along a wall rather than a share of a working bay — with the sound-attenuated cabinet holding it to 69 dB(A).\u003c\/p\u003e\u003cp\u003ePut those together and you have a compressor that can stand in the room where the work happens. Small shops rarely have a plant room to put a machine in, which is exactly why the small machines are the ones that most need to be quiet and narrow. Inside is an oil-injected rotary screw air end producing 25 CFM at 125 PSI on a continuous 100% duty cycle, tank-mounted on a 60-gallon horizontal ASME receiver. This is the 460 Volt three-phase build.\u003c\/p\u003e\u003ch3\u003eTall and narrow is a deliberate shape\u003c\/h3\u003e\u003cp\u003eMost shop compressors are laid out for a plant room, which usually means long and low. This one is arranged the other way: it stands 53.5\" high on a 23.6\" width, so it occupies a strip of wall rather than a rectangle of floor. In a two-bay workshop, a fabrication corner or a garage that is also a store, that difference decides whether the machine is in the way.\u003c\/p\u003e\u003cp\u003eIt also puts the working parts at a sensible height. The panel, the sight glass and the drain are where you can see and reach them without kneeling on a cold floor, which is the difference between a maintenance routine that happens and one that gets postponed.\u003c\/p\u003e\u003ch3\u003eQuiet enough to share a room with\u003c\/h3\u003e\u003cp\u003e69 dB(A) is roughly conversational volume. That is not silence, and a screw compressor loaded all day is still a presence — but it is a very long way from an unenclosed machine, and it is the level at which people stop arranging the workshop around the compressor. The cabinet is also doing a filtering job: it keeps grinding dust, brake dust and overspray away from the cooler and the belt drive, which are the two things that quietly cost a compressor its efficiency.\u003c\/p\u003e\u003cp\u003eSchulz publishes an ambient operating ceiling of 113 °F for this model as well, so a warm corner, an uninsulated store or a mezzanine is inside the declared operating envelope rather than a hope.\u003c\/p\u003e\u003ch3\u003eWhy 25 CFM continuous is more air than it sounds\u003c\/h3\u003e\u003cp\u003eThe 100% duty cycle rating is the specification doing the real work. A piston compressor is rated to run for a fraction of each hour, so its airflow figure is a peak you are meant to discount — and if you do not discount it, you spend the machine's service life early through heat.\u003c\/p\u003e\u003cp\u003eThis air end has no rest requirement. It is rated to run continuously, which makes 25 CFM at 125 PSI a supply figure rather than a burst figure. When you compare it with the piston machine you are replacing, compare it against that machine's \u003cem\u003eusable\u003c\/em\u003e output, not the number on its badge. The gap is usually much smaller than the specification sheets suggest, and often the wrong way round.\u003c\/p\u003e\u003ch3\u003eWill It Fit?\u003c\/h3\u003e\u003cp\u003eThe 2-in-1 layout — air end and receiver as one assembly — means a single object to place, with no separate tank and no interconnecting pipework to have fabricated. Overall it is 49.4\" long, 23.6\" wide and 53.5\" tall at 500 lbs, with a 1\/2\" tank outlet.\u003c\/p\u003e\u003cp\u003eStand it on a flat, sound slab: the load sits on the mounting feet and an uneven floor will work them loose over a season. Leave clearance around the cabinet for the cooling air it depends on, and enough room to open the panels for servicing.\u003c\/p\u003e\u003cp\u003eThe supply is 460 Volt three-phase. Schulz records both the amp draw and the recommended breaker as \"consult a certified electrician\", which is correct rather than evasive, since the cable size follows the length of the run and the local code. Confirming the supply, the panel capacity and the breaker before ordering is the customer's responsibility, and it is what usually determines whether a machine runs the week it arrives.\u003c\/p\u003e\u003ch3\u003eControl and starting\u003c\/h3\u003e\u003cp\u003eA 24 Volt microprocessor controller manages the machine, with adjustable operating parameters and a live readout instead of a gauge and an assumption — which is what makes a fault legible on a compressor that will not have a technician standing next to it. The automatic starter carries phase and sequence failure detection: on a three-phase screw, crossed phases turn the air end backwards, and a reversed screw can be ruined in seconds. The starter blocks the start rather than allowing it. A magnetic starter is fitted, and an air filter is supplied.\u003c\/p\u003e\u003ch3\u003ePerfect For\u003c\/h3\u003e\u003cul\u003e \u003cli\u003e \u003cstrong\u003eSmall workshops with no plant room\u003c\/strong\u003e — the enclosure and the narrow footprint are aimed squarely here.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eTwo-bay independents\u003c\/strong\u003e upgrading from a piston compressor that never kept up.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eBuildings already on 460 Volt three-phase\u003c\/strong\u003e that need a modest, continuous supply rather than a large one.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eFabrication corners and finishing areas\u003c\/strong\u003e where a loud machine would make the space unusable.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eAnyone tight on floor space\u003c\/strong\u003e but with wall to spare.\u003c\/li\u003e \u003c\/ul\u003e\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\u003cp\u003eThe complete factory unit: rotary screw air end, TEFC IP55 electric motor, magnetic starter with phase and sequence failure detection, 24 Volt microprocessor controller, air filter, sound-attenuated cabinet, 60-gallon horizontal ASME receiver, oil sight glass and a 1\/2\" tank outlet.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNot included:\u003c\/strong\u003e the data records no air dryer, no electronic drain valve and no pump low-oil shut-off on this model.

No independent third-party listing is recorded for the packaged machine, meaning the motor, starter, controller and cabinet assessed together as one product, and a pressure-vessel stamp does not stand in for that. We prefer to state the boundary rather than let it blur. Insurers, corporate facilities standards and some local electrical inspectors do ask for that second document on hard-wired plant. If your installation is subject to one of them, ask us before you order and we will confirm in writing what documentation currently exists.\u003c\/p\u003e\u003ch3\u003eShipping and receiving\u003c\/h3\u003e\u003cp\u003ePalletised freight throughout the lower 48 states, with the cost quoted live at checkout against your own address rather than taken from a published table.\u003c\/p\u003e\u003cp\u003eSettle the unload in advance. A carrier's obligation stops at the tailgate, so 500 lbs on a pallet needs a forklift or a dock, or a pallet jack where the ground is level and hard. Without any of those, terminal pickup lets you collect from the freight depot in your own time and with your own equipment. Deliveries to a home address are residential and carry a residential fee. Collection from our Schulz pickup point at Acworth, Georgia is also available.\u003c\/p\u003e\u003cp\u003eInspect the pallet before signing, and have any damage written onto the bill of lading while the driver is still there.

A screw air end that has already been dismantled cannot be assessed for what failed first, and the claim usually ends there.
