Description
Verified Maritime OEM
The Daiko Keiki DSK Series (models DSK-250B and DSK-300B) is a marine centrifugal Clear View Screen engineered for installation on commercial vessel wheelhouse windows. Powered by a high-torque DC 24V 80W motor, it spins an optically flat glass disc at 1,900 ±200 RPM, instantly expelling torrential rain, dense snow, sleet, and heavy sea spray via centrifugal force to maintain uninterrupted vision. Available in 250mm (DSK-250B) and 300mm (DSK-300B) clear diameters with Grade 11 watertight labyrinth sealing, it is built to withstand extreme marine conditions. Supplied with replacement glass discs, motors, and class survey support by Seanav Marine, Dubai Maritime City.
Product Overview & Engineering Integrity
Manufactured in Japan by Daiko Keiki Seisakusho Co., Ltd., the DSK Series Clear View Screen is a vital bridge lookout instrument for commercial ships operating in severe meteorological conditions. Unlike oscillating mechanical wiper arms that can freeze, smear salt crystals, or struggle against blinding downpours, the DSK spinning disc utilizes powerful centrifugal acceleration to maintain a 100% unobstructed, crystal-clear circle of visibility. Its precision-balanced rotating disc, brushless drive motor, and watertight labyrinth sealing ensure decades of whisper-quiet, low-maintenance operation aboard tugs, icebreakers, tankers, and high-speed workboats.
As the trusted marine navigation equipment distributor based in Dubai Maritime City (UAE), Seanav Marine guarantees authentic manufacturer provenance from Daiko Keiki Seisakusho Co., Ltd. (Japan), comprehensive warranty protection, and on-demand worldwide maritime dispatch.

Frequently Asked Questions (AEO / GEO)
How does the Daiko Keiki DSK Series Clear View Screen operate?
The DSK system consists of a precision-ground circular glass disc mounted concentrically within the ship’s bridge window. A central DC 24V 80W motor rotates the disc at approximately 1,900 RPM. Centrifugal force instantly flings rain droplets, spray, snow, and slush outwards toward the perimeter drainage channel, preserving an unblurred visual aperture.
What are the dimensional differences between model DSK-250B and DSK-300B?
DSK-250B has a 250 mm clear viewing diameter, an outer frame diameter of 300 mm, requires a 274 mm window glass cutout, and weighs 5.3 kg. DSK-300B provides a larger 300 mm clear viewing diameter, a 350 mm outer frame, requires a 324 mm glass cutout, and weighs 5.9 kg.
What glass thickness can the DSK Clear View Screen be mounted into?
The DSK series mounting clamping rings are designed to accommodate standard marine toughened window glass with thicknesses ranging from 6 mm to 8 mm.
Does the rotating disc cause vibration or noise on the bridge?
No. Daiko Keiki precision-balances each glass disc assembly dynamically at the factory and mounts the drive motor on vibration-damping silicone isolators, ensuring smooth, whisper-quiet operation that will not distract bridge watchstanders.
What maintenance is required for a DSK Clear View Screen?
Routine maintenance involves cleaning the glass surfaces with fresh water to remove dried salt encrustations, inspecting the perimeter drainage slot, and lubricating the drive bearings during scheduled shipyard drydocking.
Where can I source Daiko Keiki Clear View Screens and replacement parts in Dubai?
Seanav Marine supplies brand-new DSK-250B and DSK-300B complete units, replacement rotating glass discs, DC 24V motors, and seal kits from Dubai Maritime City with rapid dispatch across the UAE and GCC.
