Noise Control

PECL/PECM/PECH
Circular Elbow Silencer Packless

Packless circular elbow silencers provide a unique solution for noise control applications with round duct, where fibrous acoustic material is not permitted in the air stream, and where a 90° elbow is necessary due to space constraints.

Packless circular elbow silencers are an ideal solution for undesirable noise in applications with round duct where fibrous acoustic material is not permitted in the air stream, including computer rooms, hospitals, clean rooms, and laboratories. The elbow shape is ideal for applications with limited space where straight lengths of ductwork are not available.

  • 90° elbow is suitable for applications with limited space.
  • No acoustic media.
  • Round slip connector eliminates the need for transitions.
  • Available geometric construction options include maximum insertions loss (L), balanced performance (M), and ultra-low pressure drop (H).
  • Available in 22, 18, 16, and 10 gauge.
  • Accessories available include flanges, access doors, and drainage plugs.
