Leasing & Hire Purchase
Leasing & Hire Purchase
We offer the financing options leasing and hire purchase exclusively to businesses, commercial operators and self-employed persons for selected products with a net order value of €1,000 or more. Below you will find the key differences between the two forms of financing.
Leasing
With leasing, the product is made available to the lessee for use in return for regular lease payments. The asset is recognized on the lessor’s balance sheet. Lease payments can generally be claimed as operating expenses for tax purposes. These are gross payments, and VAT is charged throughout the entire term. Once the agreed minimum lease term has expired, purchasing the product is generally possible.
Hire purchase
In economic terms, hire purchase is equivalent to an installment purchase. The product is capitalized on the hire purchaser’s balance sheet and depreciated in accordance with the official depreciation tables. Ownership of the asset transfers to the hire purchaser upon payment of the final hire-purchase installment. VAT must be paid in full with the first hire-purchase installment (a pass-through item).

Robust construction for abrasive blasting media
During sandblasting, the blasting media used is conveyed through the hose to the blast nozzle at high speed. The hose inner tube is therefore permanently exposed to heavy abrasive stress.
The ExtraBlast features a specially designed, abrasion-resistant inner tube for this type of service. With an average abrasion value of no more than 50 mm³ according to DIN ISO 4649:2013, it offers good service life for typical industrial and craft blasting applications.
The smooth inner surface supports a consistent material flow and reduces turbulence and unnecessary flow resistance within the hose line.
Suitable for numerous blasting media
The Contracor ExtraBlast is designed for conveying highly abrasive media. These include, among others:
- Steel grit
- Angular cast steel shot
- Aluminum oxide
- Garnet sand
- Glass beads
- Mineral reusable blasting media
- Other dry and free-flowing blasting media
Whether a specific blasting medium can be used depends not only on its hardness, but also on its grain size, grain shape, bulk density, and the design of the entire blasting system.
The hose is intended exclusively for dry and sufficiently free-flowing blasting media. Damp or clumped material can impair the transport of the blasting media and cause blockages.
Antistatic hose construction
When transporting dry blasting media, friction can generate an electrostatic charge. The ExtraBlast therefore features an antistatic hose construction with an electrical resistance of less than 1 MΩ.
The antistatic design supports the controlled dissipation of electrostatic charges. This requires the hose to be properly integrated into the grounding and safety concept of the entire blasting system.
The hose, couplings, blast machine, blast gun or nozzle holder, and other conductive system components must be installed and grounded in accordance with the manufacturer's specifications.
The conductive or antistatic hose construction does not replace proper grounding of the entire blasting system. Equipotential bonding must be checked and ensured during installation.
Textile inserts for pressure resistance and stability
Woven textile inserts are positioned between the inner and outer layers. This reinforcement absorbs the compressive forces that occur during operation and stabilizes the hose against impermissible expansion.
The multilayer construction allows an operating pressure of up to 12 bar. The specified burst pressure is 36 bar, resulting in a safety factor of 3:1.
The burst pressure is not a permissible operating parameter. The hose may be used continuously only within the specified maximum operating pressure.
Which hose size is right?
The inside diameter of a sandblasting hose affects the possible air and abrasive throughput as well as the pressure loss between the blasting machine and blasting nozzle. The hose size should therefore match the nozzle size, hose length, and compressor capacity.
| Inside diameter | Typical use |
|---|---|
| 13 mm | Compact blasting machines, short hose lines, and smaller nozzles |
| 19 mm | Mobile blasting work with medium air and abrasive requirements |
| 25 mm | Professional pressure blasting machines and medium to large nozzles |
| 32 mm | High air volumes, larger nozzles, and long blast hose lines |
The inside diameter of the blast hose should typically be around three to four times the nozzle inside diameter. Longer lines may require a larger hose cross-section to limit pressure losses.
Hose diameter and pressure loss
An undersized blast hose increases flow velocity and pressure loss. As a result, less operating pressure may be available at the blasting nozzle, even if the compressor and blasting machine are adequately sized.
A larger inside diameter reduces flow resistance and can enable better performance at the nozzle, particularly with long hose lines. At the same time, a larger hose is heavier and less flexible.
The selection should therefore strike a sensible balance between air flow, hose length, maneuverability, and nozzle size.
Selecting the roll length
ExtraBlast is available in 5-, 20-, or 40-meter rolls, depending on the inside diameter. The hose length should be selected so that the intended working area can be reached without unnecessary extensions.
A longer hose line provides a larger range of movement, but also causes additional pressure losses. Excess hose length should not lie in tight loops during operation.
- 📌 5 m: short connection or compact mobile system
- 📌 20 m: typical mobile and stationary blasting applications
- 📌 40 m: large working radius or custom hose assembly
Installing hose couplings and nozzle holders
For connecting the blasting machine and blasting nozzle, blast couplings and nozzle holders matching the respective hose outside diameter are required.
The connecting fittings must be suitable for the hose type used, the outer diameter, and the maximum operating pressure. They must be installed in accordance with the manufacturer's specifications using the specified fastening screws.
A suitable coupling safety device must also be used between interconnected blast couplings. Seals, screws, and safety elements must be checked regularly for condition and secure fit.
When selecting a blast coupling or nozzle holder, not only the inner diameter but in particular the respective outer diameter of 27, 33, 39, or 48 mm is decisive.

Temperature-resistant from −30 °C to +80 °C
The ExtraBlast is designed for a wide temperature range of −30 °C to +80 °C. This allows the hose to be used both in cooler workshop and outdoor areas and at elevated ambient temperatures.
The specified temperature refers to the hose's permissible operating conditions. Additional exposure to hot workpieces, flying sparks, open flames, or aggressive chemicals must be avoided.
📌 Safety and application instructions
- Do not exceed the maximum operating pressure of 12 bar
- Inspect the hose for damage before each use
- Use only suitable couplings and nozzle holders
- Fit coupling connections with suitable safety devices
- Do not drive over the hose or crush it with heavy components
- Avoid tight kinks and severe bend radii
- Protect against sharp edges and hot surfaces
- Ensure an antistatic connection and grounding of the system
- Replace worn or damaged hoses immediately
- Fully depressurize the hose before carrying out maintenance work
Regular inspection and maintenance
Sandblasting hoses are subject to continuous internal wear caused by the abrasive flowing through them. From the outside, the hose may initially appear undamaged despite an already reduced wall thickness.
The ExtraBlast should therefore be inspected regularly along its entire length. Areas subject to particularly high stress are often located near couplings, nozzle holders, tight hose bends, and points where the hose is dragged across the floor.
- Inspect the outer cover for cuts, cracks, and abrasion
- Feel along the hose for soft or unusually thin areas
- Check that couplings and nozzle holders are securely seated
- Regularly check the fastening screws according to the manufacturer’s specifications
- Inspect seals for wear
- Check electrical conductivity and grounding connection
- Do not continue using severely worn hose sections
