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

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.

RPB Safety C40 – Air conditioner for cooling and heating supplied breathing air

The RPB Safety C40 is a compact air conditioner for supplied-air respiratory protection systems. It allows the user to adjust the temperature of the supplied breathing air directly at the belt, making work more comfortable in hot or cold working conditions.

A lever allows you to switch between cooling and heating mode. The C40 can cool the incoming breathing air by up to 29 °C or heat it by up to 18 °C. The airflow can also be adjusted using a separate regulator.

How It Works

The C40 operates according to the vortex tube principle. Part of the supplied compressed air is used for temperature separation, while the required breathing-air flow is directed to the helmet. Therefore, in addition to the air requirements of the respiratory protection system, the compressed-air supply must also cover the air conditioner's additional consumption.

📌 Important:
The C40 may only be operated within a breathing-air configuration approved by the manufacturer. An undersized compressed-air supply may result in the airflow to the helmet falling below the required level.

Maintenance and Care

✔ Clean the silencer regularly and replace it if necessary
✔ Keep the air inlet and connections clean
✔ Check the function of the temperature lever and air regulator
✔ Protect the device from abrasive media and paint mist
✔ Use only approved breathing-air hoses
