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.

Comprag D55 screw compressor – 55 kW, direct drive (1:1 drive)
The D55.. models are particularly powerful direct-drive screw compressors with a 1:1 coupling between the motor and compressor element. This lossless power transmission ensures maximum efficiency, low maintenance requirements, and a long service life. The integrated i-Log control system provides plain-text display, monitors all relevant operating parameters, and makes daily operation easier.
Comprag D Series – Industrial Efficiency in Continuous Operation
Designed for 24/7 operation in demanding environments, the D Series delivers consistently high-quality compressed air at low operating costs. The direct drive minimizes mechanical losses, the sound-insulated housing reduces noise emissions, and the multistage air/oil separation system ensures clean compressed air quality.
For the highest demands in workshops and industry:
The D55 screw compressor delivers up to 9.1 m³/min at 8 bar (or 8.5 m³/min at 10 bar). The sound-insulated design (approx. 73 dB(A)) and combined air/oil cooler ensure quiet, reliable operation—even under continuous load.
⚙️ Quality Motors
All F-Series compressors are equipped with high-efficiency quality motors from leading manufacturers. They have energy reserves, do not operate in the overload range, and are additionally protected by thermal motor protection.
🌀 Efficient Screw Element
The modern rotor design of the screw element ensures maximum energy efficiency. A thin oil film separates the rotor elements without contact, reduces friction, and ensures an exceptionally long service life.
💧 Clean Compressed Air
The oil is reliably removed through centrifugal and gravitational separation as well as high-quality air/oil separators. The residual oil content at the outlet is less than 3 mg/m³, ensuring particularly pure compressed-air quality.
