Frequently Asked Questions

What oil does this compressor use?
Schulz piston compressors use Schulz SG-TM 30 semi-synthetic compressor oil (our SS-30 product). This is the factory-recommended oil for all Schulz L-Series and V-Series piston compressors. Use of other oils may void warranty.
Is shipping included in the price?
Yes — free shipping is included to commercial locations with a loading dock or forklift. Liftgate service, inside delivery, and residential delivery are available for additional fees (shown at checkout). Standard delivery requires a commercial address.
How long does delivery take?
Most compressors ship within 1–2 business days from our warehouse. Delivery typically takes 3–7 business days depending on your location. You'll receive a tracking number when your order ships.
What is covered under warranty?
Schulz compressors include a 2-year warranty on the compressor pump and a 1-year warranty on all other components. Extended warranties (2, 3, or 5 years) are available at checkout. We are an authorized dealer, so all warranty claims are supported directly.
Do I need a special electrical setup?
Single-phase models run on standard 230V single-phase power (common in most shops). Three-phase models require 230V or 460V three-phase service. Always verify your electrical capacity before ordering — our team can help you confirm requirements by phone.
Can I return or exchange the compressor?
Please contact us before purchasing if you have sizing questions — our team can help you choose correctly. For return inquiries, contact us at info@schulzproducts.com or (770)-734-6383 within 30 days of delivery.
