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 FV55 screw compressor – 55 kW, variable-speed (frequency converter)
The FV55.. models are powerful, variable-speed screw compressors with a frequency converter. They adjust their speed precisely to the current air demand, eliminating idle times and reducing energy costs by up to 25%. Thanks to v-Log control, the FV55.. provides full transparency over all operating parameters, group control, and simple maintenance planning. With a delivery capacity of up to 9 m³/min, it is the right choice for businesses with high compressed air requirements.
Comprag FV series – Variable-speed screw compressors
The FV-series compressors are equipped with a modern frequency converter that continuously adjusts the compressor's output to the current compressed air demand. This ensures reliable operation at all times with the required amount of compressed air at constant operating pressure —and only as much energy is consumed as is actually needed. This intelligent operating principle enables maximum energy savings and makes the FV series the ideal choice for companies with varying compressed air requirements.

⚙️ Quality motors
All F-series compressors are equipped with high-efficiency, high-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 block
The modern rotor design of the screw block ensures maximum energy efficiency. A thin oil film separates the rotor elements without contact, reducing friction and ensuring an exceptionally long service life.
💧 Clean compressed air
The oil is reliably removed through centrifugal and gravity 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.
