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.

Air nozzle for GA/GX sandblasting gun, several variants - 2.4 is in stock and will be shipped as soon as it is available again
Contracor air nozzle for GA and GX sandblasting guns
The Contracor air nozzle is a suitable replacement and wear part for the GA and GX sandblasting guns in Contracor sandblasting cabinets. It guides the compressed air through a defined bore into the gun's mixing chamber, where it creates the negative pressure that draws in the abrasive and mixes it with the air stream.
The air nozzle is available in four bore sizes from 2.4 to 5.0 mm. Selecting the right version affects the compressed air requirements and must match the blast nozzle used and the available compressor capacity.
Your benefits at a glance
✅ Four bore sizes for different performance ranges
✅ Precise compressed air guidance in the mixing chamber
✅ Supports a consistent abrasive flow
✅ Quick replacement in case of wear or damage
✅ Original spare part for Contracor sandblasting cabinets
📦 Scope of delivery
Sandblasting gun, blast nozzle, nozzle holder and other components are not included in the delivery.

Technical data
| Feature | Specification |
|---|---|
| Product type | Air nozzle / Air-Jet |
| Compatibility | Contracor GA and GX |
| Bore sizes | 2.4 / 3.2 / 4.0 / 5.0 mm |
| Application range | Injector blast guns in sandblasting cabinets |
Recommended combination of air nozzle and blast nozzle
For good suction performance and a consistent abrasive flow, the air nozzle and blast nozzle should be matched to each other. As the air nozzle size increases, the possible blasting performance and the required compressed air volume flow both increase.
| Air nozzle | Suitable blast nozzle | Typical application |
|---|---|---|
| 2.4 mm | 4–5 mm | Fine work and low compressed air requirements |
| 3.2 mm | 6 mm | Smaller cabinets and medium performance range |
| 4.0 mm | 8 mm | Common standard combination for GA/GX |
| 5.0 mm | 10 mm | High blasting performance with sufficient compressor capacity |
The existing blasting gun combination should generally be retained when replacing a component. An oversized blast nozzle combined with an air jet that is too small can reduce suction performance. A larger air jet significantly increases compressed air consumption and requires a correspondingly powerful compressor.
Selecting the right air jet
A larger bore allows a higher airflow rate and can increase blasting performance, but it also requires correspondingly greater compressor capacity. A smaller air jet reduces air consumption, but also limits the maximum achievable blasting performance.
Installation and replacement
✔ Disassemble the blasting gun and remove the existing air jet
✔ Clean the mixing chamber and threads or mount
✔ Insert the new air jet fully and without tension
✔ Correctly install the blast nozzle and other components
✔ Check function and leak-tightness before regular operation
Maintenance and safety
✔ Check if the blast pattern is uneven or suction performance decreases
✔ Operate only with dry, clean compressed air
✔ Do not reuse damaged threads or mounts
✔ Perform maintenance work only on a depressurized system
FAQ – Frequently Asked Questions
Which guns is the air jet suitable for?
The variants are intended for Contracor sandblasting guns in the GA and GX series.
Which air jet is suitable for an 8 mm blast nozzle?
A 4.0 mm air jet is usually used for an 8 mm blast nozzle.
What size do I need?
The bore size must be suitable for the existing blast nozzle, the desired performance and the available compressor capacity. If in doubt, the size currently installed should be retained.
Does a larger air jet always increase performance?
Only if sufficient compressed air is available and the blast nozzle being used is compatible with it. Otherwise, the operating pressure may drop.
Is the blast nozzle included?
No. Only the selected air jet is supplied.
