Leasing & Rent-to-Own
Leasing & Rent-to-Own
We offer leasing and rent-to-own financing options exclusively to business owners, tradespeople, and the self-employed for selected products with a net merchandise value of €1,000 or more. Below you will find the key differences between these two financing options.
Leasing
In a lease, the product is made available to the lessee for use in exchange for regular lease payments. The lessor is responsible for accounting for the lease. The lease payments can generally be claimed as business expenses for tax purposes. These are gross payments, and value-added tax is charged throughout the entire term. At the end of the agreed-upon basic lease term, it is generally possible to purchase the product.
Hire Purchase
Hire purchase is economically equivalent to installment purchase. The product is capitalized on the hire purchaser’s balance sheet and depreciated in accordance with the official depreciation tables. Upon payment of the final hire purchase installment, ownership of the item is transferred to the hire purchaser. Value-added tax must be paid in full with the first hire purchase installment (transitory item).
Shipping & Delivery
Shipping & Delivery
Depending on the size, weight, and nature of our goods, they are shipped either via parcel service or freight carrier. We select the shipping method at our reasonable discretion.
The delivery times listed in the online store are non-binding estimates, unless a binding delivery date has been expressly confirmed in writing. They are based on the information available from our manufacturers, suppliers, and logistics partners at the time the order is placed.
Most of the products offered are shipped directly from the manufacturer or from external central warehouses (direct shipping). As a result, delivery times may differ from the estimated times provided. Delivery delays may occur, particularly in the event of material shortages, production delays, supply bottlenecks, force majeure, or other circumstances beyond our control.
Disclaimer:
We assume no liability for delivery delays resulting from circumstances beyond our control. This applies in particular to delays caused by manufacturers, suppliers, shipping companies, or other third parties. Liability for any resulting damages—in particular for indirect damages, consequential damages, or lost profits—is excluded to the extent permitted by law.
Partial deliveries are permitted, provided they are reasonable for the customer. This does not result in additional shipping costs, unless otherwise agreed.
The exact delivery time for an item can be provided on an individual basis upon request, either before or after the order is placed.
Please contact us by phone at +49 (0)2551 5030 or by email at shipping@strahltechnik-express.de.
In the event of significant delivery delays, we will inform the customer immediately. The customer’s mandatory statutory rights remain unaffected by this.

FBSC Venturi blast nozzle, silicon carbide, long, 50 mm coarse thread, nozzle bore 5–12.5 mm - 5 x 140 is in stock and will be shipped as soon as it is available again
Novablast FBSC Venturi blast nozzle – silicon carbide, 32 mm inlet diameter, and acetal jacket
The Novablast FBSC is a long Venturi blast nozzle designed for professional pressure blasting applications that require high surface coverage rates, a uniform blast pattern, and the lightest possible nozzle weight. The elongated Venturi profile accelerates compressed air and abrasive media in a controlled manner through the nozzle, producing a wide, uniform blast cone with high exit velocities.
This model features a 32 mm inlet diameter, a robust acetal jacket, and a wear-resistant silicon carbide nozzle insert. Silicon carbide is lighter than tungsten carbide and is therefore particularly suitable for longer manual blasting jobs where the weight of the nozzle is a factor. The connection is via a 50 mm coarse thread. Nozzle bores ranging from 5 to 12.5 mm are available.
Benefits
✅ Long Venturi geometry for high abrasive velocity and a wide blast cone
✅ Silicon carbide nozzle insert with high wear resistance
✅ Lighter weight than comparable tungsten carbide blast nozzles
✅ Particularly comfortable during longer manual blasting jobs
✅ Durable acetal jacket to protect the nozzle insert
✅ 32 mm inlet diameter for a smooth transition to the nozzle
✅ 50 mm coarse thread for compatible professional nozzle holders
✅ Nozzle bores ranging from 5 to 12.5 mm for different compressor power ratings and work tasks
✅ Variants with unique manufacturer SKUs for reliable reorders

Calculate compressed air requirements, abrasive consumption, and compressor power
Select the nozzle bore, operating pressure, and desired power reserve. The calculator displays the nozzle’s compressed air requirement, the recommended compressor free air delivery, the approximate abrasive consumption, and a guideline for the required compressor motor power.
💡 Why plan for a power reserve? Blast nozzles wear out during operation. As this happens, the nozzle bore gradually increases in size, and the required compressed air flow rate rises. A power reserve helps to compensate for this additional demand as well as for typical pressure losses in the system, ensuring that the desired blasting pressure remains stable even as nozzle wear increases.
The reserve applies exclusively to compressor sizing. Abrasive consumption remains unaffected.
The values are technical guidelines. Abrasive media consumption is an approximation based on published consumption tables for mineral abrasive media with a bulk density of approximately 1,600 kg/m³. Dosage, grit size, density, the metering valve, the hose system, and nozzle wear all influence actual consumption. The kW specification is for guidance only; the effective air flow rate at operating pressure is the determining factor for compressor selection.
How It Works and Selecting the Nozzle Size
✔ The long Venturi profile accelerates air and abrasive media in a controlled manner and supports a high exit velocity
✔ The blast pattern is designed for productive surface work and is wider than that of a simple straight nozzle bore
✔ The 32-mm inlet ensures a smooth, high-flow transition from the blast hose to the nozzle
✔ The nozzle bore directly affects air consumption, blasting capacity, and the required compressor size
✔ Smaller nozzle bores reduce the required flow rate; larger nozzle bores increase the possible surface coverage rate when there is a sufficient supply of compressed air
✔ The key factor is the actual available compressor free air delivery at operating pressure
Recommended Abrasive Media
Silicon carbide blast nozzles are particularly well-suited for abrasive mineral blasting media and applications that require high wear resistance combined with low nozzle weight. They are especially suitable for:
✔ Corundum / Aluminum Oxide
✔ Garnet abrasive
✔ Slag and other disposable mineral abrasives
✔ Glass beads
✔ Additional dry, free-flowing mineral abrasive media within the permissible grain size range
In very harsh operating conditions, with frequent impacts, or where there is an increased risk of mechanical damage, a tungsten carbide blast nozzle may be the more robust alternative.
📌 Important: The grit size and maximum particle size must be compatible with the nozzle bore, the abrasive metering valve, and the entire conveying path. Damp, clumped, or excessively coarse abrasive media can impair material flow and cause cloggings.
Applications
✔ Professional rust removal and paint stripping services
✔ Surface preparation prior to coating and corrosion protection
✔ Steel and Plant Engineering
✔ Industrial Maintenance and Repair
✔ Workshops and mobile blasting services
✔ Longer manual blasting operations where a lighter nozzle weight is advantageous
Wear, Inspection, and Operation
Silicon carbide offers high wear resistance but is structurally more brittle than tungsten carbide. The nozzle should therefore be protected from heavy impacts and falls and regularly inspected for damage.
✔ Check the nozzle bore regularly for wear
✔ Do not drop the nozzle onto hard surfaces and avoid unnecessary impact loads
✔ Take cracks, chipping, or damage to the nozzle inserts seriously and replace affected nozzles
✔ Worn nozzles increase compressed air consumption and can alter the blast pattern
✔ Check nozzle holders and threads regularly to ensure they are secure
FAQ
