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).
Shipping & Delivery
Shipping & Delivery
We ship our goods either via parcel service or via a freight forwarding company, depending on their size, weight and characteristics. We select the shipping method at our reasonable discretion.
The delivery times stated in the online shop are non-binding estimates, unless a binding delivery date has been expressly agreed in writing. They are based on the information available from our manufacturers, suppliers and logistics partners at the time the order is placed.
A large proportion of the products offered are shipped directly from the manufacturer or from external central warehouses (direct shipment). As a result, delivery times may differ from the stated guidelines. In particular, material shortages, production delays, supply bottlenecks, force majeure or other circumstances for which we are not responsible may result in delivery delays.
Disclaimer:
We accept no liability for delivery delays resulting from circumstances beyond our control. This applies in particular to delays caused by manufacturers, upstream suppliers, transport companies or other third parties. Liability for any resulting damages, in particular indirect damages, consequential damages or loss of profit, is excluded to the extent permitted by law.
Partial deliveries are permitted insofar as they are reasonable for the customer. They will not result in additional shipping costs unless otherwise agreed.
The exact delivery time for an item can be provided individually on request, either before or after placing the order.
Please contact us by telephone at +49 (0)2551 5030 or by email at shipping@strahltechnik-express.de.
If significant delivery delays occur, we will inform the customer without undue delay. Mandatory statutory rights of the customer remain unaffected.

Düsenprofi GD Double Venturi – maximum performance with hot-pressed boron carbide
The Düsenprofi GD Double Venturi sandblasting nozzle is a particularly wear-resistant long nozzle for professional pressure blasting systems. The nozzle core is made of hot-pressed boron carbide (B4C) and is designed for high loads and abrasive blasting media. The Double Venturi geometry supports a powerful blast pattern for demanding blasting work.
All GD versions feature a 32 mm inlet opening and a 50 mm aluminium coarse thread (2"). Depending on the desired surface performance and available compressor capacity, nozzle bores from 6.5 to 12.5 mm are available.

Compressor and compressed-air requirements
The required compressed-air flow rate increases significantly with the nozzle diameter and the selected working pressure. Before selecting a larger nozzle orifice, you should therefore check whether the compressor in use can continuously provide the required flow rate.
Conclusion
The Düsenprofi GD is a high-quality double Venturi blast nozzle for users who want to combine high wear resistance with professional blasting performance. Its hot-pressed boron carbide makes it particularly suitable for intensive applications with abrasive blasting media.
FAQ – frequently asked questions
What distinguishes a double Venturi nozzle from a standard Venturi nozzle?
The double Venturi geometry is designed to produce a particularly powerful and wider blast pattern.
Which nozzle orifice should be selected?
The choice depends on the desired coverage rate, working pressure, and available compressor capacity.
Does the nozzle fit into every nozzle holder?
It requires a nozzle holder for 50 mm or 2" coarse thread and a 32 mm inlet opening.
How is wear detected?
The nozzle orifice should be measured regularly. An enlarged orifice increases air consumption and changes the blast pattern.
