The device in question is a professional dispensing tool, specifically the COX AirFlow 1 (AF1) RBA 300 B, designed for the application of sealants and adhesives. It is a manual dispenser, meaning it operates without external power sources like electricity or compressed air, relying on the user's hand strength to dispense the material. The device is compatible with 310 ml cartridges, as indicated by the product name and the accompanying technical specifications.
Function Description:
The primary function of this device is to dispense viscous materials, such as sealants and adhesives, from standard 310 ml cartridges. The design incorporates a plunger mechanism that pushes the material out of the cartridge when the trigger is squeezed. The device is designed for precise and controlled application, making it suitable for professional use in various industries.
Usage Features:
- Manual Operation: The device is entirely manual, requiring no external power. This makes it highly portable and usable in environments where power sources are unavailable or inconvenient.
- Cartridge Compatibility: It is specifically designed for 310 ml cartridges, a common size for sealants and adhesives.
- Plunger Release Mechanism: The device features a plunger release button (often located at the back of the handle) that allows the user to retract the plunger, facilitating easy cartridge insertion and removal.
- Pressure Release: The design incorporates a pressure release mechanism to prevent material from oozing out after the trigger is released. This is crucial for clean application and minimizing waste. The manual explicitly mentions "Automatic pressure release" as a feature, which helps prevent unwanted material flow.
- Adjustable Flow Control: While not explicitly detailed as a separate dial, the manual operation allows for variable flow rates depending on the pressure applied to the trigger. Some models might include a flow regulator or a pressure plate adjustment for more precise control. The manual mentions a "flow regulator" in the context of maintenance, suggesting some form of flow control is present or can be adjusted.
- Robust Construction: The device appears to be constructed from durable materials, likely metal (as suggested by the industrial appearance and the "Robust construction" mention in the safety instructions), to withstand the rigors of professional use.
- Ergonomic Design: While not explicitly stated, professional tools typically incorporate ergonomic features to reduce user fatigue during prolonged use. The handle design appears to be shaped for a comfortable grip.
- Easy Cartridge Loading: The design facilitates straightforward loading and unloading of cartridges. The plunger can be retracted to insert a new cartridge, and then advanced to engage the cartridge piston.
Important Technical Specifications:
The provided documentation includes a table of "Product Type / Weight (kg)" and "PPA 700 / Weight (kg)" which likely refers to different models or configurations of the dispenser and their respective weights. For the COX AirFlow 1 (AF1) RBA 300 B, the "RBA 300 B" designation is key. While specific weight for this exact model isn't isolated in the table, similar models like "RBA 300" are listed with weights around 1.9 kg to 2.2 kg, suggesting the device is relatively lightweight for a professional tool.
- Cartridge Size: 310 ml (as per the product name and common usage for this type of dispenser).
- Material Compatibility: Designed for viscous materials like sealants and adhesives.
- Noise Emission: The manual provides detailed noise emission data, which is important for occupational safety.
- Sound pressure level, A weighted (LpA) = 78.9 dB
- Sound power level, A weighted (LWA) = 89.9 dB
- Peak C weighted sound pressure level (LpCpeak) = 78.9 dB
- Average daily exposure based on 8 hours continuous use = 78.9 dB
These values indicate that while the device itself is not excessively loud, prolonged use might necessitate hearing protection in certain environments, especially if multiple devices are in operation.
- Vibration Emission:
- Hand-arm vibration = 0.04 m/s²
This extremely low vibration level indicates that the device is designed to minimize user exposure to vibration, reducing the risk of hand-arm vibration syndrome (HAVS).
Maintenance Features:
The manual emphasizes the importance of regular maintenance for optimal performance and longevity of the device.
- Cleaning: Regular cleaning of the device is crucial. The manual advises cleaning the device after each use, particularly focusing on removing any material residue from the front of the dispenser and the plunger rod. This prevents material from hardening and obstructing the mechanism.
- Lubrication: The manual suggests lubricating moving parts, specifically the plunger rod and the internal mechanisms, to ensure smooth operation and prevent wear. The use of a suitable lubricant (e.g., silicone spray) is recommended.
- Inspection: Regular inspection of the device for wear and tear is advised. This includes checking the plunger rod, the trigger mechanism, the cartridge holder, and any seals for damage or excessive wear.
- Replacement of Worn Parts: The manual implies that certain parts, such as the plunger rod or seals, might need replacement over time due to wear. The design appears to allow for the replacement of these components, extending the lifespan of the dispenser.
- Storage: Proper storage in a clean, dry place is recommended to protect the device from damage and corrosion.
- Safety Instructions: The maintenance section is often linked with safety instructions, emphasizing that maintenance should only be performed by trained personnel and that the device should be disconnected from any power source (if applicable, though this is a manual device) before maintenance. For this manual device, ensuring it is unloaded and clean before maintenance is key.
In summary, the COX AirFlow 1 (AF1) RBA 300 B is a robust, manually operated dispensing tool designed for professional use with 310 ml cartridges of sealants and adhesives. Its key features include ease of use, precise application control, low noise and vibration emissions, and a design that facilitates straightforward maintenance, ensuring a long service life.
