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.

Contracor EDUCT-O-MATIC – portable vacuum blasting unit with a closed abrasive circuit

The Contracor EDUCT-O-MATIC is a compact, portable vacuum blasting unit for low-dust blasting of small surfaces, edges, corners and local repair areas. The unit combines vacuum blasting and abrasive recovery in one tool: reusable abrasive is continuously returned to the integrated container during operation, while dust, spent abrasive and loosened contaminants are collected in the dust bag.

The freely rotating blast head enables work upwards, downwards and sideways without having to rotate the main body of the unit. Various rubber attachments and brushes ensure that the blasting area is sealed as tightly as possible against the surface, allowing the unit to adapt to flat surfaces, edges, angles and other workpiece geometries.

Technical data
Feature Specification
Equipment type Portable vacuum blasting unit
Process Vacuum blasting with a closed abrasive circuit
Article number 10112800
Compressed-air consumption 2.5 m³/min at approx. 6.1 bar
Maximum working pressure 7 bar
Compressed-air connection KIG 1/2" claw coupling
Recommended air hose size 3/4" (19 mm), alternatively 1/2" (13 mm)
Blast nozzle 9 mm, tungsten carbide
Working width approx. 30 mm, depending on the attachment used

Suitable abrasives
Abrasive Recommended grit size Note
Steel or iron shot up to approx. 0.3 mm Particularly recommended by the manufacturer
Corundum up to approx. 0.8 mm according to the catalog Increased wear possible
General abrasives approx. 0.15–0.40 mm according to the operating instructions Dry, clean and uniformly graded
💡 Recommendation:
For good recovery, low dust generation and reduced equipment wear, Contracor recommends steel or iron shot. Very brittle abrasives break down faster and increase the amount of dust. Highly abrasive media such as corundum or silicon carbide can accelerate wear.

How the closed-loop system works

When the operating lever is fully pressed, the compressed air is divided into two streams. The first air stream generates negative pressure in the blast head, draws abrasive from the integrated container and accelerates the air-abrasive mixture through the nozzle onto the surface.

The second air stream simultaneously generates the suction effect. Abrasive, dust and detached contaminants are suctioned back into the main body through the attachment, which rests tightly on the surface. The components are separated by cyclone action: reusable abrasive falls through a sieve back into the container, while dust and light residues enter the dust bag.


Two-stage operating lever
✔ Lever partially pressed: suction function only
✔ Lever fully pressed: blasting and suction simultaneously
✔ After blasting, hold the lever in the suction position for another 2–3 seconds
✔ Residual abrasive and dust are suctioned back out of the blast head

Attachments, adapters and brushes

The EDUCT-O-MATIC can be adapted to the geometry of the workpiece using different attachments. The operating instructions list the following accessories, among others:

✔ Standard adapter
✔ Master adapter
✔ Serrated attachment
✔ Edge attachment
✔ Angled attachment
✔ Flat-lip attachment
✔ Closed blanking attachment
✔ Brush adapter
✔ Round brush
✔ Angled brush

For reliable recovery, the attachment must rest fully and tightly on the surface during blasting.


Typical areas of application
✔ Localised rust and paint removal
✔ Cleaning weld seams
✔ Preparing small repair areas
✔ Cleaning flat surfaces
✔ Working on edges, corners and angles
✔ Touch-up work on machinery, vehicles and structures
✔ Blasting work in areas where loose abrasive should be avoided as far as possible

Commissioning and operation
✔ Use dry, preferably treated compressed air
✔ Install an air filter and water separator in the supply line
✔ Fill only a small quantity of suitable abrasive
✔ Fit the appropriate attachment firmly onto the blast head
✔ Keep the device as upright as possible, with the container facing downwards
✔ Press the attachment firmly against the surface to create a tight seal before blasting
✔ After finishing, operate reverse extraction only for 2–3 seconds

Maintenance and safety
✔ Empty the dust bag regularly
✔ Check the sieve, abrasive channels and hoses for blockages
✔ Check the tungsten-carbide blast nozzle regularly for wear
✔ Check attachments and brushes for damage and sealing effectiveness
✔ Never blast without a tightly sealed adapter element
✔ Never look into the blast nozzle while the compressed air is connected
✔ Shut off the compressed-air supply and depressurise the system before carrying out maintenance work
✔ Wear suitable safety glasses, respiratory protection, hearing protection and protective clothing

FAQ – frequently asked questions

Does the device operate completely dust-free?
The closed reverse-extraction system significantly reduces escaping dust and loose abrasive. This requires the attachment used to form a tight seal against the surface.

How much compressed air is required?
The manufacturer specifies approximately 2.5 m³/min at around 6.1 bar.

Which abrasives are particularly suitable?
Contracor recommends steel or iron shot. These abrasives can be recovered efficiently and produce fewer fines than very brittle media.

Why does the lever have two stages?
The first stage activates only the extraction. When fully pressed, blasting and reverse extraction are activated simultaneously.

Which attachments are included in the delivery?
The Contracor catalogue lists six rubber attachments as well as a dust bag. Additional adapters and brushes are available as accessories or spare parts.
