LAE Pneumatic Concrete Vibrator Shaft, 6 Meter, 70mm, Made in Italy - PN70

Pneumatic Internal Vibrator 70mm

Large-scale concrete pours in civil engineering projects necessitate mechanical equipment capable of displacing substantial volumes of material efficiently. The LAE PN70 pneumatic immersion vibrator is developed specifically for these heavy-duty applications. Manufactured in Italy, this unit utilizes a heavy 70mm hardened steel vibrator head with a total bottle length of 310 mm and a localized weight of 4.8 Kg. This substantial head mass allows the tool to penetrate deep into thick concrete slabs and large bridge pillars without stalling or deflecting. The vibrator is connected to a durable, anti-abrasive 6-meter hose, giving the completely assembled 8.5 kg unit the necessary physical extension to reach the bottom of deep formworks while keeping the primary air supply system stationary.

The mechanical efficiency of this vibrator relies entirely on its robust pneumatic architecture. Calibrated for industrial air compressors, the PN70 requires a steady air pressure of 6 BAR and continuously consumes 1,200 L/min. This high-volume air intake generates a rapid vibrational frequency of 16,500 vpm. When combined with a 1 mm physical amplitude and an output of 8,000 N of centrifugal force, the vibrator actively breaks the internal friction of thick concrete mixes, ensuring dense air pockets are forced to the surface rapidly. Operating at a measured sound level of 92 dB(A), this pneumatic unit provides structural technicians with a highly dependable, wear-resistant method for consolidating high-density concrete in continuous, uninterrupted operational cycles.

Key Features & Benefits:

• High-Capacity Compaction Force: Generates a substantial 8,000 N of centrifugal force, engineered to consolidate large volumes of high-density concrete and displace stubborn air pockets in heavy structural forms.

• Extended 6-Meter Working Radius: Features a heavy-duty flexible hose measuring 6 meters in length, granting operators deep access into tall concrete columns and extensive foundations without constantly relocating the compressor.

• Industrial-Grade Frequency Output: Delivers a consistent 16,500 vpm vibrational frequency that effectively reduces the internal friction of thick concrete mixes, promoting a uniform and homogeneous structural finish.

• High-Volume Pneumatic Efficiency: Calibrated for demanding worksites, requiring a steady 1,200 L/min of air consumption at 6 BAR to sustain continuous mechanical vibration during large-scale continuous pours.

• Massive 70mm Steel Vibrator Head: The 310 mm long vibrator bottle is constructed from hardened, wear-resistant steel, utilizing its 4.8 Kg mass to maintain deep immersion in thick concrete without stalling.

• Reinforced Anti-Abrasive Hose: Manufactured with specialized external layers designed to withstand severe bending stress and constant friction against sharp steel rebar, ensuring uninterrupted internal pneumatic airflow.

• Optimal 1mm Mechanical Amplitude: Utilizes a carefully calculated 1 mm physical amplitude that accurately balances high-speed air removal with the prevention of aggregate segregation, ensuring structural integrity upon curing.

• Heavy-Duty Site Reliability: Designed purely as a mechanical pneumatic solution, completely eliminating the electrical components that often fail under the extreme physical stress of commercial concrete placement.

• Impact-Resistant Construction: Built with tempered internal steel components specifically machined to endure continuous abrasion, heavy physical impacts, and the naturally harsh conditions present in civil engineering projects.
