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.

Comprag D45 rotary screw compressor – 45 kW, direct drive (1:1 drive)
The D45.. models are powerful direct-drive rotary screw compressors with a 1:1 coupling between the electric motor and the screw airend. The loss-free power transmission ensures maximum energy efficiency, minimal maintenance, and a long service life. Thanks to the integrated i-Log controller with plain-text display, you retain full control over all operating parameters and maintenance intervals.
Comprag D Series – Industrial Efficiency in Continuous Operation
The D-Series stationary compressors are designed for continuous 24/7 operation in industrial, manufacturing, and workshop environments. The direct drive ensures loss-free power transmission, quiet operation, and exceptionally low operating costs. The robust, sound-insulated housing and multi-stage air/oil separation system ensure consistently high compressed-air quality over many years.
For the highest standards in workshops and industry:
The D45 rotary screw compressor delivers up to 7.0 m³/min at 8 bar or 6.2 m³/min at 10 bar. The sound-insulated design (approx. 72 dB(A)) and combined air/oil cooler ensure quiet, energy-efficient operation—even under continuous load.
⚙️ High-quality motors
All D-Series compressors are equipped with highly efficient, high-quality motors from leading manufacturers. They have sufficient power reserves, avoid operation in the overload range, and are protected by thermal motor protection.
🌀 Efficient screw airend
The screw airend’s modern rotor design ensures maximum energy efficiency. A thin film of oil separates the rotor elements without contact, reducing friction and supporting an exceptionally long service life.
💧 Clean compressed air
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 clean compressed-air quality.
✅ Highlights
- 1:1 direct drive – maximum energy efficiency without belt losses
- i-Log controller with plain-text display and maintenance-interval indicator
- Efficient air/oil separation < 3 mg/m³
