Leasing & Hire Purchase

We offer exclusively for entrepreneurs, traders, and self-employed individuals financing options leasing and hire purchase for selected products starting from a net goods value of €1,000. Below you will find the essential differences between both financing forms.

Leasing

In leasing, the product is made available to the lessee for use against payment of regular leasing installments. The accounting is done by the lessor. The leasing installments can usually be claimed as business expenses for tax purposes. These are gross installments, and value-added tax is incurred throughout the entire term. After the agreed basic rental period, acquisition of the product by purchase is generally possible.

Hire Purchase

Hire purchase is economically equivalent to a installment purchase. The product is activated in the balance sheet of the hire purchaser and depreciated according to the official depreciation tables. Upon payment of the last hire purchase installment, ownership of the object transfers to the hire purchaser. The value-added tax must be paid in full with the first hire purchase installment (pass-through item).

Shipping & Delivery

The shipping of our goods depends on size, weight, and nature, either via parcel service or via freight forwarding. The choice of shipping method is made by us at our discretion.

The delivery times indicated in the online shop 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 of the order.

A large part of the products offered is shipped directly from the manufacturer or from external central warehouses (direct shipping). As a result, delivery times may differ from the specified benchmarks. In particular, material shortages, production delays, delivery bottlenecks, force majeure, or other circumstances beyond our control may lead to delivery delays.

Disclaimer:

We accept no liability for delivery delays caused by circumstances that are outside our control. This particularly applies to delays caused by manufacturers, suppliers, transport companies, or other third parties. Liability for any resulting damages, especially for indirect damages, consequential damages, or lost profits, is excluded to the extent permitted by law.

Partial deliveries are permissible as long as they are reasonable for the customer. No additional shipping costs will be incurred unless otherwise agreed.

The exact delivery time of an item can be communicated individually upon request before or after the order.

Please contact us by phone at +49 (0)2551 5030 or by email at shipping@strahltechnik-express.de.

If there are significant delivery delays, we will inform the customer immediately. Mandatory legal rights of the customer remain unaffected.

Comprag D90 screw compressor – 90 kW, directly driven (1:1 drive)

The D90.. models are extremely powerful direct drive screw compressors with 1:1 coupling between motor and compression stage. The loss-free power transmission ensures maximum efficiency, minimal maintenance effort, and long service life. The integrated i-Log control monitors all relevant operating parameters and facilitates daily operation.

Comprag D series – industrial efficiency in continuous operation

Developed for 24/7 operation in production and workshops: direct drive without belt losses, sound-insulated housing, and multi-stage air/oil separation provide constant compressed air quality at low operating costs.

For the highest demands in workshops and industry:
The D90 delivers up to 15.4 m³/min at 8 bar or 13.4 m³/min at 10 bar. With a noise level of approx. 75 dB(A) and efficient cooling, the system operates quietly and reliably – even under continuous load.


⚙️ Quality motors

All compressors in the F series are equipped with highly efficient quality motors from leading manufacturers. They have energy reserves, do not operate in overload conditions, 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 providing an exceptionally long service life.

💧 Clean compressed air

Through centrifugal and gravitational separation as well as high-quality air-oil separators, the oil is reliably removed. The residual oil content at the outlet is less than 3 mg/m³ – for particularly pure compressed air quality.


✅ Highlights
  • Direct drive 1: 1 – maximum efficiency without belt losses
  • i-Log control with clear text display and service intervals
  • Multistage air/oil separation < 3 mg/m³
  • Sound-insulated, service-friendly design
  • For demanding industrial continuous operation (24/7)
