FD Mechanical Float Drain Valve, 1/2", 13 bar
The Comprag FD Series mechanical float-type condensate drain valves enable fully automatic condensate drainage without compressed air loss—completely without an electrical connection. The robust float mechanism reliably drains condensate when the fill level is reached and is also suitable for oily condensate. Thanks to its compact design, integrated purge valve, and 1/2″ threaded connection, the FD drain is ideal for compressors, compressed-air filters, dryers, and tanks. Suitable for operating pressures up to 13 bar in industrial, workshop, and trade applications.

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 FD Series – Mechanical Float-Type Condensate Drain
The Comprag FD is a mechanical float-type condensate drain for automatic drainage in compressed-air systems. It requires no electrical supply and opens according to the condensate level in the drain chamber. This makes it suitable for compressors and compressed-air treatment components where a simple, mechanically operated drain is required.
✅ Highlights
- Mechanical float-type condensate drain
- No electrical connection required
- Automatic drainage according to condensate level
- Integrated manual flush/test valve
- Suitable for oil-containing compressed-air condensate
- Compact design for compressors and treatment components
🔧 Technical Specifications
- Model: FD
- Threaded connection: G 1/2″
- Compressor capacity: 2.8 m³/min at 7 bar; 3.4 m³/min at 13 bar*
- Maximum operating pressure: 13 bar
- Dimensions (W × D × H): 110 × 135 × 130 mm

*Capacity specification when installed directly on a compressor. Application limits may differ when the drain is installed on dryers, filters or other components.
🛠️ Typical Applications
- Piston and rotary screw compressors
- Compressed-air filters
- Air dryers
- Air receivers and other condensate collection points, where compatible
❓ FAQ – Frequently Asked Questions
- Does the FD require electricity?
No. The drain operates mechanically via a float mechanism. - Can the drain be tested manually?
Yes. The integrated flush/test valve allows a manual functional check and cleaning. - Is it suitable for oil-containing condensate?
