Shipping & Freight

For an order containing products from a single brand, shipping is a flat rate based on your order total:

  • Orders up to $5,000: $279
  • Orders $5,000 to $10,000: $347
  • Orders $10,000 and over: $517

These rates cover standard freight delivery to a commercial address. After you place your order, our team will confirm your delivery timeline within 1 to 3 business days.

Ordering from more than one brand? Multi-brand orders ship on separate freight and are quoted individually rather than at the flat rate above. Place your order or contact us first and we will confirm total freight before anything is finalized.

Liftgate service is not included in these rates. If your delivery location has no loading dock or forklift to unload the freight from the truck, liftgate service is required and will be added to your shipping charge. If you are unsure whether you need it, contact us before ordering.

Commercial delivery locations are preferred when available. Residential delivery, limited-access locations, and appointment scheduling may affect handling.

Lead times vary by product, manufacturer availability, and selected options. Some configured, special-order, or non-stock items require additional processing time before they ship.

Please inspect all freight shipments at delivery before signing. If you see visible damage, note it with the carrier and contact us as soon as possible.

If you need freight, delivery, or lead-time guidance before ordering, contact our team before you purchase.

Compatibility / Fitment

Compatibility varies by product type, machine setup, selected options, and intended application.

For machine-mounted equipment and attachments, buyers should confirm fitment before ordering using the relevant machine information, including model, attachment style, mount type, coupler type, hydraulic requirements, and any other product-specific requirements listed on the page.

Hardscape Heavy can assist with pre-order fitment guidance based on the information you provide. This guidance is limited to purchase and compatibility review before ordering and does not include field installation, hydraulic modification, fabrication, or on-site setup support.

If you are unsure whether a product will work with your machine or application, contact us before placing the order.

Returns & Warranty

Warranty coverage is provided by the product manufacturer where applicable. Warranty terms, coverage periods, exclusions, and claim procedures vary by brand and product type.

Hardscape Heavy does not create separate warranty coverage beyond the manufacturer’s warranty unless explicitly stated on the product page.

Returns are governed by our store return policy. Because many products in this category involve freight shipping, special ordering, or configuration-specific selections, return eligibility may vary by product and condition. Special-order, custom-configured, used, damaged, or installed items may not be eligible for return.

Please review our full return policy before purchase. If you have questions about return eligibility or manufacturer warranty coverage for a specific item, contact us before ordering.

Mi-T-M's M-Series duplex air compressor runs two independent pump/motor assemblies on a single 120-gallon ASME tank, controlled by a 3-position switch: compressor 1 as lead, compressor 2 as lead, or automatic alternating between the two. That gives a shop the option to run on one pump while the other is available as backup or out for service, rather than losing air entirely. Start/stop control covers two separate pressure ranges rather than one, matching the lead/lag operation.

The same four features that set the M-Series simplex line apart carry over here: an air-cooled aftercooler that removes up to 65% of moisture and drops air temperature within 10°F of ambient, a low oil sensor that won't let a pump start if its oil runs low, an automatic tank drain, and vibration isolator pads. HP and voltage/phase are the core decision, same as the simplex line: 5.0 through 15.0 HP per pump, with 15 HP offered in three-phase only.

Common Applications

  • Fixed, high-volume compressed air where uptime matters, since one pump can keep running air while the other is serviced
  • Shops that need more total air capacity than a single-pump simplex unit provides at the same tank size

Selection Notes

  • HP and voltage/phase must match the electrical service available on site; 15 HP is three-phase only, with no single-phase option
  • The 3-position switch lets either pump lead or the two alternate automatically, rather than running as a fixed single unit
  • Replacement pump part numbers are shared with the simplex line (ACS/ADS/AES), matched by HP tier
