For starters: air is everywhere. In almost all food processes, even closed ones, food gets into contact with the air surrounding it.Untreated compressed air contains many potentially harmful or dangerous contaminants which must be removed or reduced to acceptable levels in order to protect the consumer and provide a safe and cost effective production lines.
Not changing filters regularly will result in over saturated filters, preventing effective removal of bacteria. This results in the consumer product becoming contaminated and unfit for consumption.
By not choosing the correct air handling, you leave yourself open to the following risks:
- Over saturated filters resulting in damage to important equipment.
- Contaminated product, resulting in products unfit for consumption
- Contaminated product going out to the public leaving the company open to possible fines and legal action
- Negative publicity if a contaminated product reaches the market
- Depending on the severity of the contamination, the whole plant could be shut down pending government investigation
All these result in a massive increase in production costs that far outweigh the yearly maintenance cost needed to make sure all the air handling equipment meets the strict guidelines for food safety.
