MEP Plumbing and HVAC Fittings Block Library with UPVC Components

This comprehensive block library contains standardized MEP fittings for plumbing and HVAC systems, focusing on UPVC components in various sizes. The collection includes pipe hubs and couplings ranging from 50mm to 160mm diameters, with special attention to transition fittings (e.g., 160-110mm, 110-50mm reductions). The drawing features detailed symbols for mechanical equipment including air handling units, fan coil units, exhaust fans, and diffusers, along with plumbing fixtures and fire protection components. The library is organized into separate sections for fire protection, plumbing, and HVAC systems with corresponding legends that define standard symbols and abbreviations. A layer control system with 152 distinct layers enables precise organization of components by system type, size, and function. The library follows metric measurements throughout and includes comprehensive technical annotations for proper implementation in building systems design.
