Lubricated Screw Air Compressor, Integrated 200L, Single‑Phase 220V, VSD — Auto‑Repair Specification & Sales Guide

A 220V single‑phase, VSD‑controlled, oil‑injected rotary screw with a 200L receiver is a strong “no three‑phase” solution for independent garages, tire shops, detailing/spray booths, body shops and mobile service bases. It replaces noisy piston banks with steady pressure, soft‑start VSD control and continuous duty, but you must size FAD to the busiest simultaneous tool load and treat air quality separately for painting.

1. What the configuration means

2. Realistic 220V single‑phase VSD screw performance

Market references for tank‑mount single‑phase PM/VSD screw:

• 4 kW / ~5 hp single‑phase, receiver‑mount: ~620 L/min @8.5 bar (example Jaguar ES‑05T).

• 5.5 kW / 7.5 hp single‑phase options:

  • PM VSD 4 kW/5.5 hp listing: 0.55 m³/min @8 bar, 0.50 @10 bar, 200L, 220V, optional refrigerated dryer/coalescing filter.

  • Oil‑injected VSD 5.5 kW, 200L, 680 L/min @7 bar, 650 @8 bar, 590 @10 bar; ~64 dB(A)±4; direct drive; optional built‑in refrigerant dryer.

  • Single‑phase PM VSD 5.5 kW 200L: up to 0.98 m³/min @7 bar, 0.95 @8, 0.92 @10, 0.84 @12 in one supplier table (varies by air‑end/overload allowance).

• 7.5 kW / 10 hp single‑phase receiver‑mount: ~700 L/min @8.5 bar (5.5 kW class example) to ~1000 L/min @8.5 bar (10 hp example).

• 5.5 kW 220V single‑phase VSD with 130L instead of 200L: published full‑load 17.8 A, 550 L/min @10 bar—useful amperage anchor, though smaller tank and different air‑end.

Practical planning values for integrated 200L oil screw on 220V:

• 4 kW class: ~0.55–0.62 m³/min at 7–8.5 bar.

• 5.5 kW class: ~0.55–0.95 m³/min at 8 bar depending on air‑end and single‑phase inverter limit; quote FAD per ISO 1217, not displacement.

• 7.5 kW class: ~0.70–1.00 m³/min at 8.5 bar, but single‑phase current is high—verify service capacity or default to 3‑phase.

3. Auto‑repair air demand — sizing the 200L VSD screw

Estimate by simultaneous tools at working pressure:

Sizing steps:

1. List tools used at once during peak bay activity.

2. Convert to FAD at working pressure, not “HP” or displacement.

3. Apply simultaneity 0.6–0.9 depending crew size.

4. Add 10–20% for dryer/filter/line loss and leaks.

5. Match VSD screw FAD:

   • 1–2 bays, impacts+tires+blowguns only → 4 kW/200L VSD often enough.

   • 2–3 bays plus sanders/spray spot → 5.5 kW/200L VSD.

   • Multi‑bay with regular spray booth or several sanders concurrent → 7.5 kW+; if 220V single‑phase service cannot carry it, quote 3‑phase 7.5–11 kW instead.

Example: two impact wrenches 2×5 CFM + sander 10 CFM + blowgun 3 CFM = 23 CFM (~650 L/min) peak, simultaneity 0.8 → ~520 L/min + 15% margin → ~600 L/min at 8 bar. A 5.5 kW VSD screw at ~650 L/min @8 bar with 200L tank fits; if sanding is continuous all day, prefer 7.5 kW or 3‑phase.

4. Why VSD + 200L suits a garage

• Stable pressure​ — VSD holds a tight band (e.g., 6.5–8.0 bar setpoint) so impact torque and spray regulation stay consistent; piston pressure swing is wider and noisier.

• Soft start on 220V​ — inverter ramp avoids DOL inrush that can trip single‑phase breakers; important when the panel also feeds lifts, chargers and lighting.

• Part‑load saving​ — garage demand swings (inflating vs sanding vs idle). VSD reduces motor speed instead of unloading; vendors cite up to ~30% energy vs fixed piston of equal output, real saving depends on daily profile.

• 200L buffer​ — covers bead‑seat spikes and multiple short impacts without spinning the drive to max every time.

• Lower noise in customer areas​ — enclosed VSD screw packages commonly 60–68 dB(A); 5.5 kW all‑in‑one references ~60–64 dB(A). Piston substitutes in garages are often much louder.

5. Air quality for auto repair — critical because “lubricated”

Oil‑injected screw output carries oil aerosol + water vapor + particulates. For a garage:

• General pneumatic tools/tires/lifts​ — aftercooler + moisture separator + basic coalescing/particulate filter. Refrigerated dryer (~+3 °C PDP) is recommended if humidity is high or tools run continuously.

• Paint/body/spray​ — treat aggressively:

  1. Aftercooler → bulk water separator/auto drain.

  2. Refrigerated dryer for general refinish; desiccant dryer (−40 °C or per paint OEM) for low‑humidity/basecoat/clear, winter or humid booths.

  3. Coalescing filter 0.01 µm / 0.01 mg oil at least for quality paint; pre‑filter 1 µm upstream.

  4. Activated carbon if oil vapor/odor matters.

  5. For high‑end waterborne/HVLP or odor‑critical booths, evaluate oil‑free scroll/screw upstream; a lubricated screw with perfect filtration can be acceptable for many refinish jobs, but “oil‑free air‑end” removes the oil‑aerosol source.

• Brake/parts washing/cleaning​ — low oil/particle class; if cleaning fluids are sensitive, use oil‑free or double‑stage filtration.

• Purity documentation: specify ISO 8573‑1 solid/water/oil classes, e.g., general garage 1.4.2 or 1.4.1; spray 1.2.1 or better depending paint spec. Lubricated screw residual oil depends on separator/filters—one 5.5 hp single‑phase listing quotes separator outlet <3 mg/m³ , but point‑of‑use after filters should be far lower.

6. 220V single‑phase electrical checklist

Single‑phase VSD screw draws significant current; verify before promising 200L/5.5–7.5 kW:

• Approximate input current depends on inverter PF, efficiency and whether the quote is motor shaft or package input. As a planning check (220V, η≈0.9, PF≈0.85–0.98 with VFD):

  • 4 kW package ≈ 21–23 A input

  • 5.5 kW package ≈ 29–33 A input for a simple estimate; a specific 5.5 kW/130L 220V VSD product is published at 17.8 A full load, showing inverter design and tank/speed affect the number.

  • 7.5 kW package ≈ 40–50+ A; many garages should use 3‑phase instead.

• Use dedicated breaker, correct cable size for run length/ambient, ground fault/earth protection per local code.

• VSD mitigates starting current vs DOL, but full‑load amps still must fit the panel alongside lifts, chargers, booth fans and heaters.

• Confirm voltage tolerance (220/230/240V, 50/60Hz), phase protection (single‑phase surge/brownout), EMC filtering and inverter enclosure IP rating for dusty garage.

• If the site has 380/400/415V 3‑phase, prefer it for 5.5–7.5 kW: simpler, cheaper per kW, better for continuous spray.

7. Integrated “all‑in‑one” options to quote

A. 2‑in‑1 / 3‑in‑1 lubricated VSD screw + 200L​

Screw host + PM/VSD motor + 200L tank; optional built‑in refrigerant dryer and filters. Good for tire/mechanic bays where paint is occasional and done with external extra filtration. OPPAIR‑style single‑phase PM VSD 5.5 kW/200L lists 0.98/0.95/0.92/0.84 m³/min at 7/8/10/12 bar, 60±2 dB, VFD start.

B. 4‑in‑1 screw + tank + dryer + filters​

Best for body/detail shops on 220V. Request dryer capacity matched to FAD at 8–10 bar, auto drain, coalescing + particulate + optional carbon, IoT controller. 5.5 kW all‑in‑one 200L with dryer can be quoted ~650 L/min @8 bar and ~64 dB(A) from comparable oil‑injected VSD models.

C. 4 kW entry garage package​

220V single‑phase PM VSD, 200L (or 120L if space‑limited), ~0.55–0.62 m³/min @8 bar, for 1–2 bays, tires, blowguns, light impact. Lower amps, easier on residential/small commercial panels.

D. 7.5 kW single‑phase only if power allows​

Receiver‑mount PM VSD 7.5 kW single‑phase references ~1000 L/min @8.5 bar with 200L+ tank. Confirm panel amps, cable and utility approval; otherwise offer 7.5 kW 3‑phase or twin 5.5 kW.

8. Maintenance for oil‑injected VSD screw

• Compressor oil: standard intervals commonly 2000–4000 h; synthetic/extended longer; first fill earlier. Single‑phase home/grage use with short hours can still age oil by moisture/time—follow OEM, not only hours.

• Oil separator: 4000–8000 h or differential alarm; affects oil carryover and pressure drop.

• Oil filter: with oil change or per 2000–4000 h.

• Intake filter: inspect monthly in dusty garage, replace 1000–2000 h; dirty intake cuts FAD and raises energy.

• Auto tank drain: daily/weekly; manual drain if no auto—200L collects condensate fast in humid spray environments.

• VSD/inverter: keep cabinet ventilated, check fan/filter, log faults, avoid dust/overspray ingress.

• Belts/coupling: many integrated single‑phase screws are direct‑drive; if belt, check tension 500–1000 h.

• Service access: integrated units save space but confirm panel/cooler/filter access before install.

220V Single‑Phase VSD Lubricated Screw Air Compressor, 200L Integrated, for Auto Repair​

All‑in‑one oil‑injected rotary screw package for garages without three‑phase power. Permanent‑magnet VSD motor, direct‑drive screw air‑end and 200L receiver deliver steady 7–10 bar air for impact wrenches, tire machines, sanders, lifts, blowguns and spot spray. Inverter control provides soft start, pressure‑band regulation and part‑load energy saving; integrated aftercooler, automatic drain and optional refrigerated dryer plus coalescing/particulate/carbon filters support dry, clean garage air.

Specifications: 4–7.5 kW single‑phase 220/230V • 5.5 kW class approx. 0.55–0.95 m³/min FAD at 7–8 bar depending air‑end (confirm ISO 1217) • 200L receiver • 7/8/10/12 bar options • oil‑injected screw, PM VSD, direct drive • air‑cooled • noise ~60–64 dB(A) for 5.5 kW enclosed units • built‑in dryer/filters optional • IoT/touchscreen optional • CE/ISO/PED options, OEM voltage and tank code customizable. For full paint‑booth work, specify desiccant dryer and 0.01 µm oil filtration or an oil‑free upstream air‑end.

Replace FAD, amps, noise and dryer PDP with factory test data; do not publish displacement as working FAD.

11. Common mistakes to avoid

• Selling “screw = paint‑ready” without dryer/filters — lubricated screw needs full treatment for body work.

• Sizing by HP/tank only — a 200L tank cannot fix low FAD; use 8‑bar FAD vs tool demand.

• Specifying 7.5 kW single‑phase 220V without checking panel amps/cable — if the service is marginal, quote 3‑phase or 5.5 kW VSD.

• Using fixed‑speed piston mindset — VSD screw saves most when garage demand varies; if tools run flat‑out 8 h straight, compare fixed vs VSD by load profile.

• Undersizing dryer for humid climates/booth — refrigerated may be enough for general tasks, but basecoat/clear/waterborne often needs desiccant.

• Ignoring oil separator condition — worn separator raises oil carryover, ruins spray finish and increases pressure drop.

• Placing VSD cabinet in overspray/dust — inverter electronics need clean, ventilated location; filter the cabinet intake.

If you give bay count, main tools (impacts/sanders/spray guns), desired pressure, daily hours, and the exact 220V service amp rating, I can fix one BOM: 4 vs 5.5 vs 7.5 kW, 200L vs larger tank, refrigerant vs desiccant dryer, filter microns and estimated single‑phase current.
