NaanDan - Aspersor de impacto Full Circle 233B 3/4" 4,0×2,5 mm em latão - 0630093

NaanDan Full Circle Impact Sprinkler 233B 3/4″ 4.0×2.5 mm Brass

With a flow rate of 2.07 m³/h and a throw radius of 15.5 m at 4 bar, the NaanDan 233B delivers broad, even coverage across large irrigated areas. Fitted with a dual 4.0×2.5 mm brass nozzle pair and a 3/4″ female BSP connection, this full-circle impact sprinkler operates reliably across a recommended pressure range of 3.0 to 5.0 bar. Its all-brass construction and time-proven impact mechanism make it a dependable choice for professional solid-set, hand-shift, and permanent irrigation systems.

Coverage & hydraulic performance

The 233B achieves high distribution uniformity at spacings up to 20 m, with throw radius scaling from 15 m at 3 bar to 16 m at 5 bar and corresponding flow rates of 1.79–2.32 m³/h. An integrated stream-straightening vane maximises range and maintains a consistent water pattern even in light wind, reducing dry spots and runoff around pool surrounds, sports turf, and amenity plantings.

Construction & nozzle system

The sprinkler body, arm, and nozzles are machined from heavy-duty brass for long service life in outdoor environments. Colour-coded bayonet nozzles click in and out without tools, making field replacements fast and error-free. A fully enclosed hammer spring is protected by a sealed red cap that keeps moisture and debris away from the drive mechanism, extending service intervals and guarding against frost damage during winter operation.

Frost protection & seasonal use

The 233B is a recognised choice for overhead frost protection in orchards, vineyards, and ornamental planting — the continuous 360° rotation cycle of approximately 45 seconds maintains a latent-heat ice layer over sensitive growth. The sealed spring cap and sand-and-dust protection sleeve ensure the unit restarts reliably at the start of each season without stripping or corrosion.
