The Fastech FIV 40 Needle Vibrator is a high-performance immersion vibrator designed for efficient concrete compaction in various construction applications. With a head diameter of 40 mm and operating at 48–55V, 3-phase AC, 200Hz, it delivers 12,000 vibrations per minute, ensuring optimal consolidation of concrete mixtures. Its robust design and lightweight construction make it ideal for use in precast wall panels, tunnel segment molds, bridge deck formworks, RCC column molds, and retaining wall formworks. The vibrator's high-frequency operation minimizes air pockets and enhances the uniformity of the concrete, leading to improved structural integrity and surface finish. Its compact size allows for easy maneuverability in confined spaces, making it a versatile tool for both large-scale infrastructure projects and specialized construction tasks.​
